if 2 men or 5 women can finish a work in 6 hours then 6 men and 10 women will finish it in
Answers
In 1 hour 5 women do 1/6 part of the work
In 1 hour 1 woman does 1/(6*5) = 1/30 part of the work
In 1 hour 10 women do (10/30)= 1/3 part of the work.
In 1 hour 2 men do 1/6 part of the work.
In 1 hour 1 man does 1/(6*2) = 1/12 part of the work
In 1 hour 6 men do (6/12) = 1/2 part of the work.
In 1 hour 6 men and 10 women together do (1/3)+(1/2)
=(2+3)/6
= 5/6 part of the work
5/6 part of the work is completed in 1 hour.
1 part of the work is completed in (6/5)
= 1 hour (1*60/5) minutes
= 1 hour 12 minutes
(Ans): 1 hour 12 minutes.
