Answer:
14 7/12 days (mixed fraction)
Step-by-step explanation:
Let Monu efficnecy = 100, then Sonu = 140
As we same amount of work is done by two guys. Workdone is the same.
Then efficiency = 1/ time
140/100 = 25/x
Solving, x = 35.
As you are told to find both person working together.
1/35 + 1/25 = 12/175
Thus both can work in 175/12 days = 14 7/12 days
