Question

8 men can do a piece of work in 5 days whereas 6 women can do the same work in 10 days . In how many days 4 men and 9 women finish the work ?

Answer 1

8 men can do work in 5 days and the same work is done in 10 days by 6 women.

Time taken by 1 men = 5/8 days

So 4 men's would take 5/8 ÷4 = 5/32 days.

Time take by one women = 10/6 = 5/3 days.

So 9 women's would take 5/3 ÷ 9

= 5/27 days.

If the question is 4 men's and 9 women's together

Then

5/32 + 5/27

(135 + 160)/ 864

= 295 /864 days
