  1. The average age of four children in a family is 12 years. If the spacing between their ages is 4 years, the age of the youngest child is ?
    1. 6 years
    2. 7 years
    3. 8 years
    4. 9 years
  1. Correct Option: A

    Let the age of youngest child be y.
    so from question y + (y + 4) + (y + 8) + (y + 12) = 4 x 12
    ⇒ 4y + 24= 48
    ∴ y = 6 years
