Question

12 men or 18 women can do work in 14 days how many days will 8 men and 16 women take to complete that work

Answer 1

Your answer is....

Consider m= unit work done by men per day, w=unit work done by women per day.

Then unitary method

12m*14=18w*14 {same work}

m/w =3/2.{efficacy of men and women to complte a work in a day}

Total work which to complete is 12×3×14.

Time taken by 8 men and 16 women is =total work/their per day work

So, 12×3×14/(8×3+16*2)

36*14/(56)=9days

They will complete work in 9 days.

Hope it helps you..............
