\/><\/figure>\r\n<\/div>\r\n\r\n\r\n\r\n<p><strong>Explanation:<\/strong><\/p>\r\n\r\n\r\n\r\n<p><br \/>Solution<br \/>In the question, we have a statement PEACOCK IS DESIGNATED AS THE NATIONAL BIRD OF INDIA<br \/>Which is coded as 5688999 35 1135556678 56 458 13666689 1334 79 13366<br \/>Also what we know is<br \/>each one letter is only coded as only one character.<br \/>Number 1 to 8 are assigned to 3 letters while 9 is assigned to only 2.<br \/>This set can be approached by comparing letters and code of one word to other.<br \/>To start, IS is coded as 35 and AS is coded as 56. S is common between these two words and so as 5 so S must be assigned to 5, I to 3 and 6 to A.<br \/>Similarly, If we compare OF with PEACOCK, we get O is coded as 9 and so F must be coded as 7.<br \/>Comparing THE with DESIGNATED, H must be 4.<br \/>Till now, we have<\/p>\r\n\r\n\r\n\r\n<p>If we cross the letters and numbers we have found then we are left with PECCK DEGNTED TE NTNL BRD ND coded as 58899 1155678 58 1668 134 16.<br \/>TE is coded as 58 and NTONL is coded as 16689 that means T must be 8 as it is the common one and so E must be 5.<br \/>PECCK is coded as 58899. If C is coded as 8 then two letters will be coded as 9. As we know O is already 9, 9 will have 3 letters that means C must be 9. E is coded as 5 so P and K must be 8.<br \/>Now the table looks like<\/p>\r\n\r\n\r\n\r\n<p>And DGND NNL BRD ND is coded as 1167 166 134 16<br \/>Moving on with similar approach of comparing, BRD is 134 and ND is 16 so D must be 1 and N must be 6.<br \/>NNL is coded as 166 and N is 6 so L must be 1.<br \/>DGND is 1167 so D must be 1 and G must be 7.<br \/>The final table is<\/p>\r\n\r\n\r\n\r\n<p>B and R can be 3 or 4 in any order.<\/p>\r\n\r\n\r\n\r\n<p class=\"has-text-color has-background has-very-light-gray-color has-very-dark-gray-background-color\">Question 1<br \/>What best can be concluded about the code for the letter L?<br \/>6<br \/>8<br \/>1 or 8<br \/>1<\/p>\r\n\r\n\r\n\r\n<p><br \/>Answer: L is coded as 1.<\/p>\r\n\r\n\r\n\r\n<p class=\"has-text-color has-background has-very-light-gray-color has-very-dark-gray-background-color\"><br \/>Question 2<br \/>What best can be concluded about the code for the letter B?<br \/>3<br \/>3 or 4<br \/>1<br \/>1 or 3 or 4<\/p>\r\n\r\n\r\n\r\n<p><br \/>Answer: 3 or 4.<\/p>\r\n\r\n\r\n\r\n<p class=\"has-text-color has-background has-very-light-gray-color has-very-dark-gray-background-color\">Question 3<br \/>For how many digits can the complete list o letters associated with that digit be identified?<br \/>1<br \/>2<br \/>0<br \/>3<\/p>\r\n\r\n\r\n\r\n<p><br \/>Answer: Only for 8 and 9 can the complete list be identified so 2.<\/p>\r\n\r\n\r\n\r\n<p class=\"has-text-color has-background has-very-light-gray-color has-very-dark-gray-background-color\">Question 4<br \/>Which set of letters CANNOT be coded with the same digit?<br \/>I, B, M<br \/>X, Y, Z<br \/>S, U, V<br \/>S, E, Z<\/p>\r\n\r\n\r\n\r\n<p><br \/>Answer: we can see that S is associated with 5 and E is also associated with 5. That means only 1 more letter can be associated with 5 so in Option 3, U and V cannot be associated with 5 so 3.

The four parameters are used to arrive at an overall score, which the agency uses to give an accreditation to the colleges. In each parameter, there are five possible letter grades given, each carrying certain points: A (50 points), B (40 points), C (30 points), D (20 points), and F (0 points). The overall score for a college is the weighted sum of the points scored in the four parameters. The weights of the parameters are 0.1, 0.2, 0.3 and 0.4 in some order, but the order is not disclosed. Accreditation is awarded based on the following scheme:\u2028\u00a0<\/p>\r\n\r\n\r\n\r\n<p class=\"has-text-color has-background has-very-light-gray-color has-very-dark-gray-background-color\">\u2028Eight colleges apply for accreditation, and receive the following grades in the four parameters (F, R, P, and I):\u2028\u00a0<\/p>\r\n\r\n\r\n\r\n<p class=\"has-text-color has-background has-very-light-gray-color has-very-dark-gray-background-color\">\u2028It is further known that in terms of overall scores:<br \/>High Q is better than Best Ed;<br \/>Best Ed is better than Cosmopolitan; and<br \/>Education Aid is better\u00a0than A-one.<\/p>\r\n\r\n\r\n\r\n<p>Solution<\/p>\r\n\r\n\r\n\r\n<div class=\"wp-block-image\">\r\n<figure class=\"alignright is-resized\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-3320\" src=\"https:\/\/iquanta.in\/blog\/wp-content\/uploads\/2018\/12\/1525808127535_I-Quanta_LogoTagline-1024x390.png\" alt=\"\" width=\"78\" height=\"29\" srcset=\"https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2018\/12\/1525808127535_I-Quanta_LogoTagline-1024x390.png 1024w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2018\/12\/1525808127535_I-Quanta_LogoTagline-300x114.png 300w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2018\/12\/1525808127535_I-Quanta_LogoTagline-768x292.png 768w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2018\/12\/1525808127535_I-Quanta_LogoTagline-1103x420.png 1103w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2018\/12\/1525808127535_I-Quanta_LogoTagline-640x244.png 640w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2018\/12\/1525808127535_I-Quanta_LogoTagline-681x259.png 681w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2018\/12\/1525808127535_I-Quanta_LogoTagline.png 1888w\" sizes=\"(max-width: 78px) 100vw, 78px\" \/><\/figure>\r\n<\/div>\r\n\r\n\r\n\r\n<p><strong>Explanation:<\/strong><\/p>\r\n\r\n\r\n\r\n<p><br \/>In this what we have to find is the weightage of the given parameters in the total score.<br \/>We start using point 2, Best Ed is better than Cosmopolitan. Comparing the rating of these two, we see that they are rated equal in two parameters while equally different (one higher and one lower) in other two parameters. As they are rated similarly, there scores must be same too but Best Ed is rated better than Cosmopolitan that means that the parameter in which Best Ed is rated higher, must carry more weight than the parameter in which Cosmopolitan is rated higher.<br \/>And so R &gt; I<br \/>Similarly using point 3 that is education aid is better than A-One, we can see I &gt; P.<br \/>Now using point 1 that is High Q is better than Best Ed, We see High Q is rated better than Best Ed in only 1 parameter that is I while Best Ed is rated better in 2 these are F and R.<br \/>Now we know R &gt; I &gt; P. F and R both cannot be better than I because then Best will have higher overall score definitely so we have two possible cases R&gt;I&gt;F&gt;P and R&gt;I&gt;P&gt;F.<br \/>Calculating their scores as per the table 2, In first case, High Q\u2019s overall rating is 8+12+6+2=28 and Best Ed\u2019s Rating is 12+6+8+3=29.<br \/>In Second case, High Q\u2019s rating is 8+12+4+3=27 and Best Ed\u2019s score is 12+6+4+4=26.<br \/>So R&gt;I&gt;P&gt;F is true. That means weight of R is 0.4, I is 0.3, P is 0.2, F is 0.1.<br \/>Now we can remake the table as<\/p>\r\n\r\n\r\n\r\n<p class=\"has-text-color has-background has-very-light-gray-color has-very-dark-gray-background-color\">Question 1<br \/>What is the weight of the faculty quality parameter? <br \/>0.3<br \/>0.4<br \/>0.1<br \/>0.2<\/p>\r\n\r\n\r\n\r\n<p><br \/>Answer: As per our solution, 0.1 is the weight of Faculty.<\/p>\r\n\r\n\r\n\r\n<p class=\"has-text-color has-background has-very-light-gray-color has-very-dark-gray-background-color\">Question 2<br \/>How many colleges receive the accreditation of AAA?<br \/>Answer: By the table, 3 colleges got more than 45 that is AAA rating.<br \/>Question 3<br \/>What is the highest overall score among the eight colleges?<\/p>\r\n\r\n\r\n\r\n<p><br \/>Answer: By the table, 48 is the highest score.<\/p>\r\n\r\n\r\n\r\n<p class=\"has-text-color has-background has-very-light-gray-color has-very-dark-gray-background-color\">Question 4<br \/>How many colleges have overall scores between 31 and 40, both inclusive?<br \/>3<br \/>1<br \/>0<br \/>2<\/p>\r\n\r\n\r\n\r\n<p><br \/>Answer: No colleges scored between 31 and 40.

In each zone, we see how many products they have (Number of blocks) and how much revenue they generate (area of the blocks)<\/p>\r\n\r\n\r\n\r\n<p>Now point 1, Alfa Bravo had same number of products in Blockbuster category. As there are two unknown blocks in that category, Alfa and Bravo cannot have 3 each because for that we need 3 blank blocks. So they must have 2 each and the other blank block must belong to Charlie.<br \/>Also by point 6, Charlie had higher revenue than Bravo in this category. This is possible if the block of area 4 goes to Bravo and block with area 9 goes to Charlie.<br \/>Similarly by point 2, Alfa has more products than Charlie while Charlie had more products than Bravo. We have 3 blank blocks in the No-Hope zone. They can be distributed as 1 to Alfa and 2 to Charlie to satisfy the condition.<br \/>By point 7, Bravo and Charlie had same revenue in No-Hope category. As we know Bravo had a revenue of 4 and no new addition is done to him, the products Charlie receive must be 3+1.<br \/>Similarly by the combination of 4 and 5, we can figure out that in doubtful category, Alfa gets 2 blocks of 1+6 and Bravo gets 1 of 9.<br \/>By Point 3, Alfa, Bravo and Charlie must have 1 product each in Promising category.<br \/>Further by point 8, Alfa had a revenue of 29 in other 3 blocks and Charlie had revenue of 21. So in promising category, Alfa must get block of area 1 and Charlie must get a block of area 9.<br \/>The final table is like this.<\/p>\r\n\r\n\r\n\r\n<p class=\"has-text-color has-background has-very-light-gray-color has-very-dark-gray-background-color\">Question 1<br \/>Considering all companies&#8217; products, which product category had the highest revenue?<br \/>No-Hope<br \/>Doubtful<br \/>Promising<br \/>Blockbuster<\/p>\r\n\r\n\r\n\r\n<p><br \/>Answer: By the table above, Blockbuster had the highest revenue that is 36.<\/p>\r\n\r\n\r\n\r\n<p class=\"has-text-color has-background has-very-light-gray-color has-very-dark-gray-background-color\">Question 2<br \/>Which of the following is the correct sequence of numbers of products Bravo had in No-hope, Doubtful, Promising and Blockbuster categories respectively?<br \/>1, 3, 1, 3<br \/>2, 3, 1, 2<br \/>3, 3, 1, 2<br \/>1, 3, 1, 2<\/p>\r\n\r\n\r\n\r\n<p><br \/>Answer: In No-Hope, Doubtful, Promising and Blockbuster categories, Bravo had 1, 3, 1, 2 products respectively so option 4.<\/p>\r\n\r\n\r\n\r\n<p class=\"has-text-color has-background has-very-light-gray-color has-very-dark-gray-background-color\">Question 3<br \/>Which of the following statements is NOT correct?<\/p>\r\n\r\n\r\n\r\n<ol>\r\n<li>The total revenue from No-hope products was less than the total revenue from Doubtful products<\/li>\r\n<li>Bravo&#8217;s revenue from Blockbuster products was greater than Alfa&#8217;s revenue from Doubtful products<\/li>\r\n<li>Alfa&#8217;s revenue from Blockbuster products was the same as Charlie&#8217;s revenue from Promising products<\/li>\r\n<li>Bravo and Charlie had the same revenues from No-hope products<\/li>\r\n<\/ol>\r\n\r\n\r\n\r\n<p>Answer: Option 2, Bravo\u2019s revenue from Blockbuster was 10 which was less than Alfa\u2019s revenue from Doubtful products which is 12.<\/p>\r\n\r\n\r\n\r\n<p class=\"has-text-color has-background has-very-light-gray-color has-very-dark-gray-background-color\">Question 4<br \/>If the smallest box on the grid is equivalent to revenue of Rs.1 crore, then what approximately was the total revenue of Bravo in Rs. crore?<br \/>24<br \/>30<br \/>40<br \/>34<\/p>\r\n\r\n\r\n\r\n<p><br \/>Answer: In this, we have taken the area of 1 as revenue of 1 crore. So total revenue of Bravo becomes 17 + 3 + 4 + 10 = 34 that is the option 4.<\/p>\r\n\r\n\r\n\r\n<p class=\"has-text-color has-background has-very-light-gray-color has-very-dark-gray-background-color\">Set 5<br \/>Fun Sports (FS) provides training in three sports \u2013 Gilli-danda (G), Kho-Kho (K), and Ludo (L). Currently it has an enrollment of 39 students each of whom is enrolled in at least one of the three sports. The following details are known:<br \/>The number of students enrolled only in L is double the number of students enrolled in all the three sports.<br \/>There are a total of 17 students enrolled in G.<br \/>The number of students enrolled only in G is one less than the number of students enrolled only in L.<br \/>The number of students enrolled only in K is equal to the number of students who are enrolled in both K and L.<br \/>The maximum student enrollment is in L.<br \/>Ten students enrolled in G are also enrolled in at least one more sport.<\/p>\r\n\r\n\r\n\r\n<p><br \/>Solution<br \/>This is a question of venn diagram.<br \/>By point 1, number of students enrolled only in L is double of the number of students enrolled in all 3 sports. So we assume those playing all three as X then those playing only Ludo becomes 2X.<br \/>By point 3, the number of students enrolled in G is one less than those playing only L. By previous point, only L is 2X and hence number of students playing only G becomes 2X \u2013 1.<br \/>By point 2, 17 students are playing G in total.<br \/>The venn that we have now is<\/p>\r\n\r\n\r\n\r\n<p>Gilli-Danda (17)<br \/>Kho-Kho<br \/>Ludo<\/p>\r\n\r\n\r\n\r\n<p>X<\/p>\r\n\r\n\r\n\r\n<p>2X<\/p>\r\n\r\n\r\n\r\n<p>By point 6, we get that those who are enrolled in G and one more sport are 10. That as we know that total number of students in G is 17, the number of those playing only G becomes 17 \u2013 10=7<br \/>Now as those playing only G were 2X \u2013 1. Value of X turns out to be 4 (2X \u2013 1 = 7).<br \/>Hence, those playing all three are 4 and only L are 8.<br \/>By point 4, we get the number of students playing K and L (includes all three) is equal to the number of students playing only K. If we assume those playing only K as Y then those playing K and L but not G becomes Y \u2013 4 (4 is all three).<br \/>The venn now is<\/p>\r\n\r\n\r\n\r\n<p>Gilli-Danda (17)<br \/>Kho-Kho<br \/>Ludo<br \/>4<br \/>8<br \/>9<br \/>5 In this, we see that Y, Y-4 and 8 constitute 22 students as this area is total minus G that is 39 \u2013 17=22.<br \/>Equating we get the value of Y=9.<\/p>\r\n\r\n\r\n\r\n<p>Now, we see that the two remaining sections of the Venn must be equal to 6 in total.<br \/>Also, point 5 says that maximum students are in L. Hence those playing L and G but not K must be 4, 5 or 6 while those playing G and K but not L can be 0, 1 or 2. Otherwise those playing will be more than L. So number of students in L can be 21-23.<\/p>\r\n\r\n\r\n\r\n<p class=\"has-text-color has-background has-very-light-gray-color has-very-dark-gray-background-color\">Question 1<br \/>What is the minimum number of students enrolled in both G and L but not in K?<\/p>\r\n\r\n\r\n\r\n<p><br \/>Answer: As we see in the end, minimum value of L and G but not K is 4.<\/p>\r\n\r\n\r\n\r\n<p class=\"has-text-color has-background has-very-light-gray-color has-very-dark-gray-background-color\">Question 2<br \/>If the numbers of students enrolled in K and L are in the ratio 19:22, then what is the number of students enrolled in L?<br \/>18<br \/>22<br \/>19<br \/>17<\/p>\r\n\r\n\r\n\r\n<p><br \/>Answer: students enrolled in K and L are in the ratio of 19:22. That means the numbers of students in K will be 19 and L will be 22.<\/p>\r\n\r\n\r\n\r\n<p class=\"has-text-color has-background has-very-light-gray-color has-very-dark-gray-background-color\">Question 3<br \/>Due to academic pressure, students who were enrolled in all three sports were asked to withdraw from one of the three sports. After the withdrawal, the number of students enrolled in G was six less than the number of students enrolled in L, while the number of students enrolled in K went down by one. After the withdrawal, how many students were enrolled in both G and K?<\/p>\r\n\r\n\r\n\r\n<p><br \/>Answer: Students enrolled in K went down by 1. That means that 1 students joined L and G but not K section. Other 3 might have gone to G and K or L and K section.<br \/>Total number of students in L and G is 39 \u2013 9=28 as 9 is the number of people enrolled only in K.<br \/>As we know that number of students enrolled in G is 6 less than L and their sum is 28 while number of students liking both of them is 5, 6 or 7 (+1 to original possible numbers).<br \/>This is only possible if the common number of students is 6 otherwise number of students in G and L will be in decimals. So number of students in G becomes 15 and number of students in L becomes 21.<br \/>So the number of students in G and K previously becomes 1 and 1 added after the transfer so answer is 2.<\/p>\r\n\r\n\r\n\r\n<p class=\"has-text-color has-background has-very-light-gray-color has-very-dark-gray-background-color\">Question 4<br \/>8<br \/>7<br \/>5<br \/>6<\/p>\r\n\r\n\r\n\r\n<p><br \/>Answer: By the above explanation, Students in G and L will be 6.<\/p>\r\n<p><a href=\"https:\/\/www.iquanta.in\/\"><img decoding=\"async\" class=\"alignnone wp-image-7740 size-full\" src=\"https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2021\/12\/WhatsApp-Image-2021-12-16-at-4.09.20-PM-1.jpeg\" alt=\"CAT exam\" width=\"1280\" height=\"242\" srcset=\"https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2021\/12\/WhatsApp-Image-2021-12-16-at-4.09.20-PM-1.jpeg 1280w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2021\/12\/WhatsApp-Image-2021-12-16-at-4.09.20-PM-1-300x57.jpeg 300w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2021\/12\/WhatsApp-Image-2021-12-16-at-4.09.20-PM-1-1024x194.jpeg 1024w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2021\/12\/WhatsApp-Image-2021-12-16-at-4.09.20-PM-1-768x145.jpeg 768w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2021\/12\/WhatsApp-Image-2021-12-16-at-4.09.20-PM-1-640x121.jpeg 640w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2021\/12\/WhatsApp-Image-2021-12-16-at-4.09.20-PM-1-681x129.jpeg 681w\" sizes=\"(max-width: 1280px) 100vw, 1280px\" \/><\/a><\/p>\r\n\r\n\r\n\r\n\r\n\r\n<p class=\"has-text-color has-background has-very-light-gray-color has-very-dark-gray-background-color\">Set 6<br \/>There are only four brands of entry-level smartphones called Azra, Bysi, Cxqi, and Dipq in a country.\u2028Details about their market share, unit selling price, and profitability (defined as the profit as a percentage of the revenue) for the year 2016 are given in the table below:\u2028\u2028In 2017, sales volume of entry-level smartphones grew by 40% as compared to that in 2016. Cxqi offered a 40% discount on its unit selling price in 2017, which resulted in a 15% increase in its market share. Each of the other three brands lost 5% market share. However, the profitability of Cxqi came down to half of its value in 2016. The unit selling prices of the other three brands and their profitability values remained the same in 2017 as they were in 2016.\u2028\u00a0<\/p>\r\n\r\n\r\n\r\n<p>Solution<\/p>\r\n\r\n\r\n\r\n<div class=\"wp-block-image\">\r\n<figure class=\"alignright is-resized\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-3320\" src=\"https:\/\/iquanta.in\/blog\/wp-content\/uploads\/2018\/12\/1525808127535_I-Quanta_LogoTagline-1024x390.png\" alt=\"\" width=\"76\" height=\"28\" srcset=\"https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2018\/12\/1525808127535_I-Quanta_LogoTagline-1024x390.png 1024w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2018\/12\/1525808127535_I-Quanta_LogoTagline-300x114.png 300w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2018\/12\/1525808127535_I-Quanta_LogoTagline-768x292.png 768w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2018\/12\/1525808127535_I-Quanta_LogoTagline-1103x420.png 1103w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2018\/12\/1525808127535_I-Quanta_LogoTagline-640x244.png 640w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2018\/12\/1525808127535_I-Quanta_LogoTagline-681x259.png 681w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2018\/12\/1525808127535_I-Quanta_LogoTagline.png 1888w\" sizes=\"(max-width: 76px) 100vw, 76px\" \/><\/figure>\r\n<\/div>\r\n\r\n\r\n\r\n<p><strong>Explanation:<\/strong><\/p>\r\n\r\n\r\n\r\n<p><br \/>We remake the table including the data of 2017.<br \/>Let the initial market equal to 100.

Currency exchange outlets buy currency at buying exchange rates that are lower than base exchange rates, and sell currency at selling exchange rates that are higher than base exchange rates.\u2028\u2028A currency exchange outlet uses the local currency L to buy and sell three international currencies A, B, and C, but does not exchange one international currency directly with another.\u00a0The Base Exchange rates of A, B and C with respect to L are in the ratio 100:120:1. The buying exchange rates of each of A, B, and C with respect to L are 5% below the corresponding Base Exchange rates, and their selling exchange rates are 10% above their corresponding Base Exchange rates.\u2028The following facts are known about the outlet on a particular day:<br \/>The amount of L used by the outlet to buy C equals the amount of L it received by selling C.<br \/>The amounts of L used by the outlet to buy A and B are in the ratio 5:3.<br \/>The amounts of L the outlet received from the sales of A and B are in the ratio 5:9.<br \/>The outlet received 88000 units of\u00a0L by selling A during the day.<br \/>The outlet started the day with some amount of L, 2500 units of A, 4800 units of B, and 48000 units of C.<br \/>The outlet ended the day with some amount of L, 3300 units of A, 4800 units of B, and 51000 units of C.<\/p>\r\n\r\n\r\n\r\n<p>Solution<\/p>\r\n\r\n\r\n\r\n<div class=\"wp-block-image\">\r\n<figure class=\"alignright is-resized\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-3320\" src=\"https:\/\/iquanta.in\/blog\/wp-content\/uploads\/2018\/12\/1525808127535_I-Quanta_LogoTagline-1024x390.png\" alt=\"\" width=\"79\" height=\"29\" srcset=\"https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2018\/12\/1525808127535_I-Quanta_LogoTagline-1024x390.png 1024w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2018\/12\/1525808127535_I-Quanta_LogoTagline-300x114.png 300w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2018\/12\/1525808127535_I-Quanta_LogoTagline-768x292.png 768w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2018\/12\/1525808127535_I-Quanta_LogoTagline-1103x420.png 1103w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2018\/12\/1525808127535_I-Quanta_LogoTagline-640x244.png 640w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2018\/12\/1525808127535_I-Quanta_LogoTagline-681x259.png 681w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2018\/12\/1525808127535_I-Quanta_LogoTagline.png 1888w\" sizes=\"(max-width: 79px) 100vw, 79px\" \/><\/figure>\r\n<\/div>\r\n\r\n\r\n\r\n<p><strong>Explanation:<\/strong><\/p>\r\n\r\n\r\n\r\n<p><br \/>The exchange rates as per given in the question are<\/p>\r\n\r\n\r\n\r\n<p>We are assuming x as base values are not absolute values but ratios.<\/p>\r\n\r\n\r\n\r\n<p>Now using the points the table for outlets is<\/p>\r\n\r\n\r\n\r\n<p>Now in outlet C, we know that the amount of L used to buy and sell currency C is equal. Buying and Selling exchange rates of Currency C are 0.95x and 1.1x that is in the ratio 0f 19:22. As they are equal, the amount of currency C bought and sold must be in 22:19 so that the amount of L will be equal.<br \/>We also know that the currency C bought was 3,000 more than C sold there is 3,000 difference between initial and final amount of C.<br \/>This means that Currency C bought and sold must be 22,000 and 19,000. And the values of these will be 20,900x and 20,900x that is amount of C * exchange rate.<br \/>We can also see in the table that amount of Currency A bought is 800 more than sold (final amount minus initial amount) and amount of B bought is equal to sold. We assume these values as \u2018a\u2019 and \u2018b\u2019.<br \/>By the points in the question, we also know that the amount of L used in Buying A and B are in the ratio 5:3 and Selling A and B are in the ratio 5:9.<br \/>Filling the table with this Data<\/p>\r\n\r\n\r\n\r\n<p>The amounts in brackets are the value of currency bought and sold in terms of Local currency.<br \/>By the points in the question, we also know that the amount of L used in Selling A and B are in the ratio 5:9.<br \/>That means 110ax and 132bx are in the ratio of 5:9.<br \/>Equating these we get 110ax\/132bx=5\/9<br \/>Solving we get a:b=2:3.<br \/>Taking a=2m and b=3m and filling the table again.<\/p>\r\n\r\n\r\n\r\n<p>We also know that amount of L used in buying A and B is in the ratio 5:3.<br \/>Using this, (190mx+76000x)\/342mx = 5\/3<br \/>Solving we get m = 200.<br \/>Editing the table again.<\/p>\r\n\r\n\r\n\r\n<p>By the 4th point of the set, we get the value of 44,000x as 88,000.<br \/>So X = 2.<br \/>Final table is looks like this now.<\/p>\r\n\r\n\r\n\r\n<p class=\"has-text-color has-background has-very-light-gray-color has-very-dark-gray-background-color\">Question 1<br \/>How many units of currency A did the outlet buy on that day?<\/p>\r\n\r\n\r\n\r\n<p><br \/>Answer: By the table, we get 1200.<\/p>\r\n\r\n\r\n\r\n<p class=\"has-text-color has-background has-very-light-gray-color has-very-dark-gray-background-color\">Question 2<br \/>How many units of currency C did the outlet sell on that day?<br \/>3000<br \/>6000<br \/>22000<br \/>19000<\/p>\r\n\r\n\r\n\r\n<p><br \/>Answer: By the table, 19,000.<\/p>\r\n\r\n\r\n\r\n<p class=\"has-text-color has-background has-very-light-gray-color has-very-dark-gray-background-color\">Question 3<br \/>What was the base exchange rate of currency B with respect to currency L on that day?<\/p>\r\n\r\n\r\n\r\n<p><br \/>Answer: The exchange rate of B to L was 120x and as we know x=2, the exchange rate becomes 240x.<\/p>\r\n\r\n\r\n\r\n<p class=\"has-text-color has-background has-very-light-gray-color has-very-dark-gray-background-color\">Question 4<br \/>What was the buying exchange rate of currency C with respect to currency L on that day?<br \/>2.20<br \/>1.10<br \/>0.95<br \/>1.90<\/p>\r\n\r\n\r\n\r\n<p><br \/>Answer: Buying exchange rate of C with respect to L was 0.95x. the value of X=2 then the answer would be 1.9<\/p>\r\n\r\n\r\n\r\n<p class=\"has-text-color has-background has-very-light-gray-color has-very-dark-gray-background-color\">Set 8<br \/>Seven candidates,\u00a0Akil, Balaram, Chitra, Divya, Erina, Fatima, and Ganeshan, were invited to interview for a position.
