Question

A and B can complete a work in 10 days and 15 days, respectively. They got a total of Rs. 1,250 for that work. What will be B’s share?

• A. Rs. 400
• B. Rs. 500
• C. Rs. 600
• D. Rs. 200

Answer 1

Answer:

B. Rs. 500

Total work = LCM of 10, 15 = 30 Efficiency of A = Total work / Time taken = 30 / 10 = 3 Efficiency of B = Total work / Time taken = 30 / 15 = 2 The efficiency of both = Efficiency of A + Efficiency of B = 3 + 2 = 5 Amount per day = Total amount / Efficiency of both = 1250 / 5 = Rs. 250 The amount B get = Amount per day x Efficiency of B = 250 x 2 = Rs. 500
