  • Numerical Ability - Problems on Ages
Question

Three years ago the average age of Mohan’s family having 5 members was 17 years. Mohan becomes father but the average age of his family is same today. What is the present age of baby?

  • A) 1 year
  • B) 2 years
  • C) 3 years
  • D) 4 years
  • E) 5 years
Solution

Ans.B

The age of 5 members 3 years ago=17×5=85 years
Total age of 5 members at present= 85 + (5×3)=100
years
Total age of 6 members at present =17×6=102 years…
(as average is same at present so we took 17)
Hence, age of baby = 102-100 = 2 years
