The sum of the ages of 5 children born at the intervals of 2 years each is 60 years. What is the age of the youngest child?1). 4 years2). 8 years3). 10 years4). 12 years

Answer»

Let the AGE of children’ s be x, x + 2, x + 4, x + 6, x + 8

⇒ Sum of age = 60

⇒ x + x + 2 + x + 4 + x + 6 + x + 8 = 60

5X + 20 = 60

⇒ 5x = 40

⇒ x = 8

∴ Age of youngest child = x = 8 years
