Hello Aspirant

Let the efficiency of one man be M and that of one woman be W.

Total work done = (4M + 8W) * 10 = 40M + 80W

Also, total work done = (5M + 24W) * 4 = 20M + 96W

Therefore, 40M + 80W = 20M + 96W

20M = 16W

M/W = 4/5

Let the total work done be 1 unit. 1 unit of work is done by 4 men and 8 women in 10 days.

Efficiency of 4 men and 8 women = 1/10

Efficiency of 1 man and 1 woman = (1/10) * (1/9) = 1/90

Time taken by 1 man and 1 woman to complete 1 unit of work = 90 days

The answer is 90 days.
