Answer 2

Answer:

Step-by-step explanation:

Ratio of their time is 16:27:36 (S:B:P)

Ratio of efficiency will be inverse of time ratio... So ratio of efficiency will be - 1/16 : 1/27 : 1/36 (S:B:P)

Or 27:16:12

Now for a unit hour.. Suppose they do work 27x, 16x & 12x units respectively.... In 24 hrs they'll do (27+16+12)x * 24 = 55x*24 units...

P will complete the work in (55x*24) /12x. = 110 hours
