    C Rs.720 Correct Answer Incorrect Answer
    D Rs.1000 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let the total work be 60 units. (LCM of 12 and 30) Efficiency of A = 60/12 = 5 units/day Efficiency of B = (60/30) × (70/100) = 7/5 units/day Ratio of the efficiency of A : B = 5 : 7/5 = 25:7 Share of A = (25/32) × 1504 = Rs.1175
