Question

if 18 men can complete a work in 42 hours then how many man will be required to do same work in 54 hours?​

Answer 1

Answer:

13 men

Step-by-step explanation:

The work requires 18×42 = 756 man-hours.

If the work is to be finished in 36 days it needs 756 man-hours/54 hours = 13 men.

Since from 18 men only 5 more men need to be reduced.
