The sum of the ages of 5 children born at the interval of 3 years each is 50 years . The age of youngest child is:
-
- 10 years
- 8 years
- 4 years
- None of these
Correct Option: C
Let us assume the age of youngest child be P years.
Then according to question,
The age of 5 children born after every 3 years will be P , P + 3,
P + 6, P + 9, P + 12.
Now as we know from the given question
The sum of the ages of 5 children born at the interval of 3 years each is 50 years
P + (P + 3) + (P + 6) + (P + 9) + (P + 12) = 50
⇒ 5P + 30 = 50
⇒ 5P = 20
∴ P = 4 years
