Question

24. If 3 men or 4 women can build a wall
in 43 days, then the number of days
taken by 7 men and 5 women to build
the same wall is​

Answer 1

Answer:

3 men = 4 women.

1 man = 4/3 women.

7 man = 28/3 women.

7 men and 5 women = 5 + (28/3) = 43/3 women.

4 women can plough field in 43 days.

So, 

1 women can plough in = 43 *4 days. 

Hence, 

43/3 women can plough = (43*4 *3) /43 = 12 days.
