Question

A can do a piece of work in 10 days and b can do it in 15 days.they work for 5 days .the rest of the work was finished be c in 2 days .if they get rs 1500 for the whole work ,the daily wages of b and c ate?

Answer 1

Part of work can be done by A in one day=1/10
B =1/15
Let C can do a piece of work in x days
So part of the work can be done by C in one day=1/x
A and B work for 5 days
So part of work completed by them
5/10+5/15=(15+10)/30=25/30
=5/6
Remaining work=1-5/6=1/6
This completed by C in two days
2/x=1/6
x=12 days(days in which he alone can finish all the work)
Now let daily wages be y
So 5y+5y+2y=1500
12y=1500
y=125
Full wages took by them
A=625
B=625
C=250
