they take together to complete the work?
a) 8 (b) 6 (c) 3 (d) 2.​

Answer 1

Answer:

Step-by-step explanation:

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

=10 days working together……………..
