Question

A can do a work in 15 days B can do it in 10 days.They worked together for 2 days and then B goes away.In how many days will A finish the remaining work​

Answer 1

Answer:

(A+B)'s  1 day's work =(151+101)=61

Work done by A and B in 2 days =(61×2)=31

Remaining work =(1−31)=32

Now , 151 work is done byA in 1 day,

∴32 work done by A in (15×32)=10 days
