Question : 29 of 30

Marks: +1, -0

Five men or 10 women can do a piece of work in 15 days. How long will 5 men and 5 women take to do the same work?

Solution:

Work done by 5 men in one day =

1/{15}

Work done by 5 women in one day =

1/{30}

Work done by 5 men and 5 women in one day
=

1/{15}+1/{30}

{2+1}/{30}

3/{30}

1/{10}

So, 5 men and 5 women will finish the work in 10 days.
