Quantitative Aptitude ( CCS) Problems based on Ages

The ratio between the present age of X and Y is 4 : 5. After 3 years X’s age will be 31 years. What was Y’s age 4 years ago ?

Let's solve the problem step by step :

- The ratio between the present ages of X and Y is given as 4:5.

- Let the present age of X be 4k and the present age of Y be 5k.

- After 3 years, X's age will be 31 years. So, 4k + 3 = 31.

- Solving for k : 4k + 3 = 31 => k = 7

- Thus, Y's present age is 5k = 5 * 7 = 35.

- Y's age 4 years ago was 35 - 4 = 31.

- Option 2 (31) is the correct option.
