Question

Question 2
Mahesh and Ramesh can finish a piece of
work in 12 days, Ramesh and Satish finish in
15 days while Satish and Mahesh can finish
it in 20 days.
All the three started the work but Ramesh
left after two days. After working for four
more days, Satish also leaves. In how many
more days will Mahesh finish the work?​

Answer 1

Answer:

Ramesh can finish in 25 days. Mahesh is 50% more efficient, so he can finish in 25/1.5, or 16.67 days. Let R be Ramesh, and M be Mahesh. Then:

25R=1

50M/3=1

So:

50R=2

50M=3

50(R+M)=5

R+M=50/5
