    A Rs.432 Correct Answer Incorrect Answer
    B Rs.440 Correct Answer Incorrect Answer
    C Rs.500 Correct Answer Incorrect Answer
    D Rs.665 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Profit ratio of P, Q, R

    = {(1500×6) + (1200×6)} : {(1800×6) + (1000×6)} : {(2100×6) + (1500×6)}

    = (9000 + 7200) : (10800 + 6000) : (12600 + 9000)

    = 16200 : 16800 : 21600

    = 27 : 28 : 36

    R's profit = 660 × (36 / (27 + 28)) = 660 × (36 / 55) = Rs. 432
