    The income of A and B are in the ratio 5: 3. The expenses of A, B and C are in the ratio of 8: 5: 2. If C spends 2000 and B saves Rs. 700, then A saves:

    Solutions

    Ratio of incomes of A & B are = 5 : 3

    Ratio of expenses of A, B & C = 8 : 5 : 2

    C’s expenditure = Rs. 2000

    ∴ B’s expenditure =  5/2 × C’s expenditure

    =  5/2 × Rs.2000 = Rs.5000

    B’s saving = Rs. 700

    B’s income = Expenditure + saving

    = Rs. 5000 + Rs. 700

    = Rs. 5700

    A’s Income  =  5/3 of B’s income

    =  5/3 × Rs. 5700 = Rs. 9500

     A’s Expenditure  =  8/2 of C’s expenditure

    =  8/2 × Rs. 2000 = Rs. 8000

    ∴ A’s savings = Rs. 9500 – Rs. 8000

    = Rs. 1500
