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. 3
- B. 3
- C. 3
- D. 3
Answer: Option B
Explanation:
Let the age of the youngest child be x years
Then x+(x+3)+(x+6)+(x+9)+(x+12)=50

∴ Age of the youngest child is 4 years.
