Explanation:
Time taken by A to do the work = 5 hours
Work done by A in 1 hour
Time taken by B to do the work = 9 hours
Work done by B in 1 hour
Time taken by C to do the work = 15 hours
Work done by C in 1 hour
Therefore, remaining work
Work done by A and B together in 1 hour
Therefore, time taken by A and B to do the remaining work
Answer: 3 days
