Pawan can do a work in 20 days. Karthik can do the same work in 12 days and Rohan can do the same in 16 days. Karthik and Rohan start the work and leave after 6 days. Pawan finishes the remaining work in X days. What is the value of X?
Karthik and Rohan complete 6/12+6/16=7/8 part of the work, leaving 1/8 of the work incomplete. If Pawan spends 20 days for full work then:
20-1 x-1/8
x=20*1/8=2.5 days for remaining work
The answer is 2.5 days
