Question

2 men or women can finish work
in 10 days. How long will 6 men and
18 women take to finish the same
work?​

Answer 1

Answer:

12 men can do the job in 10 days. That means one man can do 1/(12*10) or 1/120 of the job per day.

15 women can do the job in 10 days. So one woman can do 1/(15*10) or 1/150 of the job per day.

7 men and 10 women will do 7/120 + 10/150 of the job per day. 7/120=35/600 and 10/150=40/600. So 35/600 + 40/600 or 75/600 or 1/8 of the work will be done each day.

It will take 8 days for the team to finish the job.
