    Solutions

    A sum of ₹31866 is divided between A, B and C such that the ratio of shares of A and B is 9 : 8 and that of A and C is 4 : 5.

    A : B = 9 : 8

    ⇒ A : B = 36 : 32 …………(1)

    Now, A : C = 4 : 5

    ⇒ A : C = 36 : 45 ………..(2)

    From (1) and (2)

    ⇒ A : B : C = 36 : 32 : 45

    Share (in₹) of B =
