Ramesh can do 20% more work as Mohan can do in same time. If Mohan can finish the work in 30 hours then Ramesh with the help of Mohan, can finish the same work in how many hours ?

Detailed Solution for AIIMS CRE Electrical JE/AE Mock Test- 8 - Question 2
Mohan can complete a work in 30 hours.

Ramesh can do 6/5 work in 30 hours.

So Ramesh can complete the work in 30 x (5/6) = 25 hours.

Together they can finish 1/30 + 1/25 of work in 1 hour, i.e., 11/150.

So in 150/11 hours, they will finish the work together.
