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

Explanation:

5 children born at the intervals of 3 years...

x , x + 3 , x + 6, x + 9, x + 12

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

5x + 30 = 50

5x = 50 - 30

5x = 20

x = 20/5

x = 4 <==== the youngest is gonna be 4

x + 3 = 4 + 3 = 7.....this is kid 2

x + 6 = 4 + 6 = 10....this is kid 3

x + 9 = 4 + 9 = 13....this is kid 4

x + 12 = 4 + 12 = 16....this is kid 5
