Q9 of 24 Page 213

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?

Since 3 women’s work = 5 girls work.


∴ 1 women’s work


∴ 7 women’s work


∴ 7 women’s and 11 girls work


Since 5 girls can do the work in 17 days.


∴ 1 girl will do the work in 17 x 5 = 85 days.





∴ 7 women and 11 girls working together take days.
