According to the question
According to the question
Average age of a family of 5 members 3 year ago = 17 years
sum of ages of a family members = 5×175×17 = 85 years
A baby having been born the average age of the family is same today.
Sum of age of a family of 6 members = 17×617×6 = 102 years
sum of age of a family of 5 members at present = 85+5×3=85+1585+5×3=85+15 = 100 years
Age of Child = 102 - 100 = 2 years
