Ratio and Proportion Aptitude Test Paper 11) A: B: C is in the ratio of 3: 2: 5. How much money will C get out of Rs 1260?
Answer: D Explanation: C's share = [C's ratio/ sum of ratios] * total amount 2) If a: b is 3: 4 and b: c is 2: 5. Find a: b: c.
Answer: C Explanation: The ratio of a: b is 3: 4 Note: To find the ratio in such questions, multiply a to b, then b to b, and then b to c. a: b: c = 3*2: 4*2: 4*5 3) A: B is 1: 2; B: C is 3: 2 and C: D is 1:3. Find A: B: C: D.
Answer: A Explanation: ATQ, Note: To understand the shortcut, remember you need to make the right-hand side missing numbers the same as that of last given number, and for the left-hand side the same is done. i.e., C: D will contain 2: 2 because 2 is the last number on the right side. Or, A: B: C: D Now, multiply vertically and get A: B: C: D. So, A: B: C: D = (1*3*1): (2*3*1): (2*2*1): (2*2*3) 4) 5600 is to be divided into A, B, C, and D in such a way that the ratio of share of A: B is 1: 2, B: C is 3: 1, and C: D is 2: 3. Find the sum of (A and C) and (B and C).
Answer: D Explanation: ATQ, Note: To understand the shortcut, remember you need to make the right-hand side missing numbers the same as that of last given number, and for the right-hand side the same is done. i.e., C: D will contain 2: 2 because 2 is the last number on the right side. Or, A: B: C: D Now, multiply vertically and to get A: B: C: D. So, A: B: C: D = (1*3*2): (2*3*2): (2*1*2): (2*1*3) Now, the share of A and C = [(A+C)/ (A+B+C+D)] * total amount Solution 2: Find A: B: C: D Now, multiply vertically and get A: B: C: D. So, A: B: C: D = (1*3*2): (2*3*2): (2*1*2): (2*1*3) Sum of the ratios = 3+6+2+3 = 14, but ATQ, it is 5600 Rs. Now, the share of (A+C) = 1200+800 = 2000 5) The ratio of the total amount distributed in all the males and females as salary is 6: 5. The ratio of the salary of each male and female is 2: 3. Find the ratio of the no. of males and females.
Answer: D Explanation: The total salary of males: the total salary of females = 6:5 To find the number of men and women, divide the total salary of males and females by salary of each male and female.
