Ratio of Present age of A and B = 5 : 3
The difference between the age of A 10 years hence and the age of B 4 years ago = 20 years
Calculation:
Let the Present age of A and B be 5x and 3x respectively
⇒ The age of A 10 years hence = 5x + 10
⇒ The age of B 4 years ago = 3x - 4
Now, the difference:
(5x + 10) - (3x - 4) = 20
⇒ 2x + 14 = 20
⇒ 2x = 6
⇒ x = 3
∴ The present age of A = 5x = 5 × 3 = 15 years
