The sum of ages of 5 children born at the intervals of three years each is 50 years what is the age of the youngest child?
- A. 4 years
- B. 4 years
- C. 4 years
- D. 4 years
Answer: Option A
Explanation:
Let the ages of Kunal and Sugar 6 years ago be 6x and 5x years respectively.
Then, {(6x + 6) + 4}/{(5x + 6) + 4} = 11/10
⇒10(6x + 10) = 11(5x + 10)
⇒5x = 10
⇒x = 1
∴ Sagar's present age = (5x + 6) = 16 years.
Then, {(6x + 6) + 4}/{(5x + 6) + 4} = 11/10
⇒10(6x + 10) = 11(5x + 10)
⇒5x = 10
⇒x = 1
∴ Sagar's present age = (5x + 6) = 16 years.
