Question

A can do a job in 6 days and B alone can do it in 8 days. A and B undertook to do it for ₹ 320. with the help of C they finish it in 3 days. how much to paid C ?​

Answer 1

One day's work of A =1/6

One day's work of B=1/8

One day's work of A,B and C =1/3

One day's work of C =1/3-(1/6+1/8) =1/24

The money is to be distributed in ratio of 1/6:1/8:1/24 or 4:3:1

C's share = (1/8) X 3200 = 400
