Question

4 men or 5 women can construct a wall in 82 days. How long will it take 5 men and 4 women to do the same work?

Answer 1

Answer:

4M = 5W

M/W = 5/4

Total work = (4*5*82)

Done by (5M+4W) in = 5*5+4*4 = 41 unit per day.

Time to complete whole work = 4*5*82/41 = 40 days .

4M = 5W

M/W = 5/4

Total work = (4*5*82)

Time to complete whole work = 4*5*82/41 = 40 days .
