Question

if 10 men or 12 women can finish a work in 34 hour in how many hour 12 men and 6 women will finish the same work​

Answer 1

Step-by-step explanation:

Let work done by men in a day be x and that of women be y.

10/x+12/y=1/34.

12x+10y=xy/34.

xy=408x+340y.---1.

Let m be the required hours to finish the work in 2nd case.

12/x+6/y=1/m.

6x+12y=xy/m.

6mx+12my=xy----2.

By comparing equation 1 and 2.

6m=408,m=68.

Therefore,the required answer is 68 hours.
