Answers
Given : naresha can work in 50 days. dinesh complete in 45 days if he work with naresha .
To find : if Dinesh work for 90 days , how long will naresh has to work
Solution:
naresh can work in 50 days
=> Naresh 1 Day work = 1/50
Dinesh Completes in 45 Days iof he work with naresh
=> Dinesh 1 day work = 1/45 - 1/50
=> Dinesh 1 day work = (10 - 9)/450 = 1/450
=> Dinesh alone complete in 450 days
Work done by Dinesh in 90 days = 90/450 = 1/5
(1/5) work done by Naresh in (1/5)50 = 10 Day
Number of Days taken by Naresh to do remaining work = 50- 10 = 40 Days
Naresh will work for 40 Days to complete work
& Naresh will do work in 10 days what Dinesh do in 90 days
