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

Answer»

Given 3 women or 5 girls cqn complete

a piece of work in 17 days.

3women = 5 girls

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

convert both in either of women or girls.

7 women + 11 girls

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

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

work in .......

If 5 girls finish the work in 17 days

68/3 girls finish the same work in

( 68 / 3 ) × 17 /5

= 1156 /15 days.
