Pipes And Cisterns Q2

2. A can do a work in 10 days and B can do it in 30 days and C in 60 days. If the total wages for the work  is Rs. 1800 what is the share of A?

A.Rs. 1500                                                  B.Rs. 1200

C.Rs. 2000                                                  D.Rs.1800

Answer:

Ratio of wages = 1/10 : 1/30 : 1/60 = 6 : 2 : 1  (Multiplying each term by LCM 60)

So total 9 equal parts in Rs. 1800 => each part = Rs. 200 => share of A = 6 parts = Rs. 1200.
