The sum of the ages of 5 children born at intervals of 2 years each is 40 years. What is the age of the eldest child?
12 years
The correct answer is Option 2 i.e. 12 years.
Let the age of the youngest child be x years
The ages of 5 children are x, (x + 2), (x + 4), (x + 6), (x + 8)
⇒ x + x + 2 + x + 4 + x + 6 + x + 8 = 40
⇒ 5x + 20 = 40
⇒ 5x = 20
⇒ x = 4
The age of eldest child = x + 8 = 4 + 8 = 12 years
