To do a certain work, A and B work on alternate days, with B beginning the work on the first day. A can finish the work alone in 48 days and B can finish the work alone in 32 days. How many days taken by A and B to finish the work?
Answer & explanation
Correct answer: option 1
1st day work (B) = 3
2nd day work (A) = 2
2 days work = 5
↓ ↓
38 95
Remaining work = 96 - 95 = 1
Remaining work to be done by B in = \(\frac{1}{3}\) day
Total time = 38 + \(\frac{1}{3}\) = 38\(\frac{1}{3}\) days
