IIFT 2021 (23rd Dec)
From the above information, we can say that Rahul, Sohan and Ram take 12, 18 and 10 days respectively to complete the work alone.
LCM(12, 18, 10)= 180
Let the total work be 180 units
So Work done by Rahul in 1 day = 15 units
Work done by Sohan in 1 day = 10 units
Work done by Ram in 1 day = 18 units
Let the time taken by Sohan to complete the remaining work be x days.
Therefore, 180 = 3*(15+10+18) + 10x
or, 180 = 129 - 10x
or, x= 5.1 days
