Question

The sum of ages of 5 children born at the intervals of 3 years each is 50 years. What is the age of the youngest child?

Answer 1

x+(x+3)+(x+6)+(x+9)+(x+12)=50
=> x=20/5
=4 years
Therefore, age of youngest child=4 years 0 months

Answer 2

Answer:

Let the ages of children be x, (x + 3), (x + 6), (x + 9), (x + 12) years.

According to Question now,

➳ x + (x + 3) + (x + 6) + (x + 9) + (x + 12) = 50

➳ 5x + 30 = 50

➳ 5x = 50 - 30

➳ x = 20/5

➳ x = 4 years

Therefore,the age of youngest child is 4 years.
