A and B can do a work in 25 days and 10 days respectively. A starts the work and B joins him after 2 days. In how many days can they complete the remaining work?
Answer/Solution
4.28 days
Steps/Work
Work done by A in 2 days = 2/5
Remaining work = 3/5
Work done by both A and B in one day = 1/25 + 1/10 = 7/50
Remaining work = 3/5 * 50/7 = 4.28 days.

Work done by both A and B in one day = 1/25 + 1/10 = 7/50
