Q.

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 ?                         
A. 4 Years B. 8 Yeras
C. 10 Years D. None of these

Answer: Option A
Explaination:

 


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


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

5x = 20

x = 4

Age of the youngest child = x = 4 years.
