Ages of A and B differ by 6 and are in the ratio 3 : 5. What is the sum of their ages?

Correct option is B

Given:

Ages of A and B differ by 6 and are in the ratio 3:5.

​Solution:​

Let the ages of A and B be 3x and 5x respectively.

Given that their age difference is 6:

5x – 3x = 6

2x = 6

x = 3

sum of ages = 5x+3x = 8x = 83 =24 years.
