Total work = LCM of 20 and 25 = 100
One day work of Raja = 5
One day work of Ramesh = 4
Work done by Ramesh in 10 days = 10×4 = 40
Remaining work = 100-40 = 60
Both will take days in complete the work together = 60/(4+5) = 60/9 = 20/3
It means total days = 10+20/3 = 50/3 = 16.67 days
I hope it will be helpful for you ✌️✌️
