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
⇒ 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
