Question

Neeraj can do a piece of work in 25 days and Vineeth can finish the same work in 20 days they worked together for 5 days and then Neeraj goes away in how many days will win 8 finish the remaining work​

Answer 1

work done by neeraj in 1 day = 1/25

work done by vineeth in 1 day = 1/20

work done by them in one day = 1/20+1/25

=5/100+4/100

9/100

now work done by them in 5 days =9/100*5

=45/100

=9/20

now work remaining = 20/20-9/20

=) 11/20

=) now vineeth does work in 1 day = 1/20

then work done to complete the work = 11/20÷1/20

=11

Answer =) vineeth will do the remaining work in 11 days
