∴ Quantity-I < Quantity-II Quantity - I Let the present ages of A and B be 4x and 5x.
4x+5
5x+5
=
5
6
∴ x = 5 ∴ A's present age = 20 yrs Quantity - II Average age of A, B and C = 24 years Total = 24 × 3 = 72 years Average age of B and C = 20 years Total age of B and C = 20 × 2 = 40 Age of A = 72 – 40 = 32 years
