    Question

    Rs. 5625 is divided among A, B and C so that A receives

    one half as much as B and C together receive and B receives one-fourth of what A and C together receive. The share of A is more than that of B by:
    A Rs. 750 Correct Answer Incorrect Answer
    B Rs. 775 Correct Answer Incorrect Answer
    C Rs. 1500 Correct Answer Incorrect Answer
    D Rs. 160 Correct Answer Incorrect Answer

    Solution

    Total = Rs. 5625

    A = (1/2}) x (B + C)

    B = (1/4}) x (A + C)

    Let B = x

    A + C = 4 x ⇒C = 4x – A …(1)


    A = 1/2 (B + C) = 1/2 (x + C) ⇒ 2A = x + C ….(2)

    Substitute C from (1) into (2):

    2A = x + (4x − A) ⇒ 2A = 5x – A


    ⇒ 3A = 5x ⇒A = 5x/3

    Now, C = 4x – A = 4x − 5x/3 = (12x − 5x)/3 = 7x/3

    A + B + C = (5x/3) + x + (7x/3) = 15x/3 =5x


    5x = 5625 ⇒x = 1125


    A = 5x/3 = (5 × 1125)/3 =1875


    A – B = 1875 – 1125 = 750
