A alone can do a piece of work in 6 days and B alone in 8 days. A and B undertook to do it for Rs. 3200. With
the help of C, they completed the work in 3 days. How much is to be paid to C?
Rs. 375
Rs. 400
Rs. 600
Rs. 800
Explanation:
C`s 1 day`s work = 1/3 - (1/6 + 1/8) = 1/3 - 7/24 = 1/24
A`s wages : B`s wages : C`s wages
1/6 : 1/8 : 1/24 = 4:3:1
C`s share = 1/8 $\times$ 3200 = Rs. 400
C`s 1 day`s work = 1/3 - (1/6 + 1/8) = 1/3 - 7/24 = 1/24
A`s wages : B`s wages : C`s wages
1/6 : 1/8 : 1/24 = 4:3:1
C`s share = 1/8 $\times$ 3200 = Rs. 400
