    ক)
    6 years
    খ)
    8 years
    গ)
    10 years
    ঘ)
    12 years

    Explanation

    Let, their ages are 7x, 3x ATQ, (7x + 6)/(3x + 6) = 5/3 ⇒ 3(7x + 6) = 5(3x + 6) ⇒ 21x + 18 = 15x + 30 ⇒ 21x - 15x = 30 - 18 ⇒ 6x = 12 ∴ x = 2 The difference in their ages is, = 7x - 3x = 4x = 4 × 2 = 8 years
