    B 38 days Correct Answer Incorrect Answer
    C 36 days Correct Answer Incorrect Answer
    D 30 days Correct Answer Incorrect Answer

    Solution

    Ratio of efficiency of P and Q = 6:5 Let the efficiency of P and Q be 6x and 5x units per day respectively. Total work = 11x × 25 = 275x units Required time = (0.60 × 275x)/5x = 33 days
