A can do a piece of work in 12 days and B can do it in 15 days. They work together for 4 days and then A leaves. In how many days will B finish the remaining work alone?

4 days
4.
6 days
Correct Answer: 6 days
Work done in 4 days = 4 x (1/12 + 1/15) = 3/5. Remaining work = 2/5, so B alone takes (2/5) x 15 = 6 days. / 4 दिनों में कार्य = 4 x (1/12 + 1/15) = 3/5। शेष कार्य = 2/5; अकेले B को (2/5) x 15 = 6 दिन लगेंगे।
