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 years | | [C]. |
10 years | [D]. |
None of these |
Answer: Option A
Explanation:
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.
