Question

if 3 women or 5 girls take 17 days to complete a piece of work, how long will 7 women and 11 girls working together take to complete the work?

Answer 1

Hi,

I think there is an error in the data.

But the method of solving the problem

is as follows,

Given 3 women or 5 girls cqn complete

a piece of work in 17 days.

3women = 5 girls

1 women = 5/3 girls -------( 1 )

Now we have to convert both in either

of women or girls.

7 women + 11 girls

= 7 × (5/3)girls + 11 girls [ from ( 1 ) ]

= ( 35 + 33 ) / 3 = 68/3 girls can complete the

work in how many days .

If 5 girls can finish the work in 17 days

Then 68/3 girls can finish the same work

in how many days

( 68 / 3 ) × 17 /5 = 1156 /15 days.

I hope this helps you.

:)
