    Question

    'A' and 'B' alone can complete a work in 10 days and 15

    days, respectively. If they worked together and total wage received by them to complete the work is Rs. 600, then find the wage received by 'A'.
    A Rs. 240 Correct Answer Incorrect Answer
    B Rs. 360 Correct Answer Incorrect Answer
    C Rs. 200 Correct Answer Incorrect Answer
    D Rs. 400 Correct Answer Incorrect Answer

    Solution

    Let total work = 30 units {LCM of 10 and 15} Efficiency of 'A' = 3 units per day Efficiency of 'B' = 2 units per day Since, they completed the whole work together therefore ratio of wage received by them will be same as the ratio of their efficiencies. So, Required wage received by 'A' = {3/(3 + 2)} X 600 = Rs. 360
