2. 21 years
3. 24 years
4. 25 years
5. 23 years

Answer 1

Correct Answer - Option 4 : 25 years

GIVEN:

Ages are consecutive odd numbers.

Youngest : Oldest (5 years ago) = 4 : 5

EXPLANATION:
Let the ages be x, x + 2, x + 4

A.T.Q

(x - 5)/(x + 4 - 5) = 4/5

⇒ 5x - 25 = 4x - 4

⇒ x = 21 years

Required age = 21 + 2 + 2 = 25 years

∴ The answer is 25 years.
