Correct Answer - Option 2 : 23 years
Given:
The present age of Ena is 13 year
Calculation:
⇒ The present age of Ena's mother = 13 + 24 = 37 years
⇒ The present age of Ena's father = 37 + 3 = 40 years
⇒ The age of Ena's father when he gets married = 40 - 13 - 4 = 23 years
∴ The required result will be 23 years.
