    Question

    'L' and 'K' used Rs. 12,500 and Rs. 15,000,

    respectively, to launch their businesses. 6 months later, 'L' added Rs. 2,500 to his investment, and 'J' joined them with Rs. 'a'. Find the value of 'a' if, at the end of the year, 'L's profit share is one-third of the total profit received.
    A Rs.28,000 Correct Answer Incorrect Answer
    B Rs.37,500 Correct Answer Incorrect Answer
    C Rs.21,000 Correct Answer Incorrect Answer
    D Rs.25,000 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ, Ratio of profit shares of L, K and J respectively: = [(12,500 × 6) + (12,500 + 2,500) × 6]:[15,000 × 12]:[a × 6] = (12,500 + 15,000) :(15,000 × 2) :(a) = 27,500:30,000:a So, 27,500 ÷ (27,500 + 30,000 + a) = (1/3) Or, 82,500 = 57,500 + a So, 'a' = 25,000
