Question

A B and C can do a piece of work in 10 days A alone do the work in 40 days and B alone do the work in 30 days in how many days c will do the work​

Answer 1

Step-by-step explanation:

Work done by A,B,C in 1d= 1/10

Work done by A in 1d= 1/40

Work done by B in 1d= 1/30

Work done by C in 1d= 1/10-(1/30+1/40)=5/120=1/24

So,C alone takes 24 days to finish the work
