1. 20 years
2. 15 years 
3. 25 years
4. None of the above

Answer 1

Correct Answer - Option 1 : 20 years

Given:

Ratio of ages of Subhash and Ravi = 4 ∶ 5

Calculation:

Let present ages of Subhash and Ravi be 4a years and 5a years respectively.

⇒ 4a = 5a - 5

⇒ a = 5

∴ Present age of Subhash = 5 × 4 = 20 years
