    Question

    A invested Rs. (P + 1200). After 3 months, B joined with

    Rs. 3P. If B’s share to A’s share of the annual profit is 9:5, determine (P − 600).
    A 4,200 Correct Answer Incorrect Answer
    B 8,500 Correct Answer Incorrect Answer
    C 3,750 Correct Answer Incorrect Answer
    D 1,460 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Ratio of profit share of A and B respectively:

    = [(P + 1200) × 12] : [3P × 9]

    = (12P + 14400) : 27P

    = (4P + 4800) : 9P (dividing by 3)

    ATQ;

    (4P + 4800) : 9P = 5 : 9

    Or, 4P + 4800 = 5P

    Or, P = 4800

    Required value = 4800 − 600 = 4200
