Answer 1

Correct Answer - Option 1 : 2 years

Given 

Dinesh was married at the age = 27 years 

Formula Used 

Average = sum of data/No. of data

Calculation 

Total age of Dinesh, his wife and his son after 6 years of marriage = 22 × 3 = 66 years 

⇒ According to Question 

⇒ 33 + 29 + x = 66 

⇒ x = 4 

So, his son after 6 years of marriage = 4 years 

then, his son was born 2 years after marriage 

∴ The Dinesh's son born after 2 years of his marriage
