Answer:
7 days and 12 hours
Step-by-step explanation:
Given,
Time taken by A to do the piece of work = 15 days
Since, B is 50 % more efficient than A it will do the piece of work in half the time taken by A to do the same piece of work.
Hence,
Time taken by B to do the piece of work = 1/2 of ( Time taken by A to do the piece of work )
Time taken by B to do the piece of work = 1/2 of 15 days
Time taken by B to do the piece of work = 15 / 2 days
Time taken by B to do the piece of work = 7.5 days
Time taken by B to do the piece of work = 7 days and 12 hours
