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 )
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.
