  1. The ages of A and B are in the ratio 2 : 5. After 8 years their ages will be in the ratio 1 : 2. The difference of their ages is ?
    1. 20 years
    2. 24 years
    3. 26 years
    4. 29 years
Correct Option: B

Let the current ages of A and B be 2x and 5x respectively
Now from question (2x + 8) / (5x + 8) = 1 / 2
⇒ 2(2x + 8) = (5x + 8)
⇒ x = 8
∴ Difference of their ages = (5x - 2x) = 3x = 24 years
