Question

4 men or 6 women can do a work in 42days.. The number of days 12 men and 3 women would take of finish the work.. solution​

Answer 1

Answer:

Step-by-step explanation:

first multiply both 4 men and 6 women

then, 12 men and 3 women

now,

         24:42

         36:x

now, cross multiply both of them

24x = 42 * 36

x = 42 * 36

    ------------

        24

when you cancel all three you will be left out with

9 * 7 = 63

therefore, the number of days 12 men or 3 women would take to finish the work is 63 days.

Answer 2

Answer:

Let the amount of work done by 1 man in a day be m, and that done by 1 woman be w.

Now, 4m=6w

Or, w= 2m/3 -(1)

Also, amount of work done by 4 men in a day =4m

Or 4m= 1/42

Or, m= 1/168 -(2)

Using (1) and (2), amount of work done by 12 men and 3 women in a day is 12m+3w

=12m+2m (substituting w from 1)

=14m

=14/168

=1/12

So, the total work will be completed in 12 days.
