Ram and Shyam can complete a task in days and 15 days, respectively. They work together for 4 days, and then Ram leaves. In how many days after Ram leaves, will Shyam complete the remaining task alone?
1.5 days
3 days
4 days
2 days
Let the total work be 60 units.
( L.C.M. of ( = 20/3) and 15 is 60.)
Efficiency of Ram = work/time = = 9 units/day
Efficiency of Shyam = 60/15 = 4 units/day
Work done by Ram and Shyam in 4 days = efficiency time = (9 + 4) 4 = 52 units
Remaining work = 60 - 52 = 8 units
Time taken by Shyam to complete the remaining work = 8/4 = 2 days
