Correct Answer - Option 2 : 2 years

**Given **

The average age of Raju's family 3 years ago = 14 years

**Formula Used **

Average = sum of observation/No. of observation

**Calculation **

Let the age of his daughter is X years.

Three years ago, sum of ages of all four family members = 14 × 4 = 56 years

Today the total age of the 4 members of the family is

⇒ 56 + (4 × 3) = 68 years

A girl having been born, the average of the family is same today 14yr

⇒ 14 = (68 + X)/5

⇒ 68 + X = 70

⇒ X = 2

**∴ The age of his daughter is 2 years.**
