Answer 1

Answer:

Direct and Inverse Variation | Direct and Inverse Variation Exercise 9.3. 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? ∴ 7 women and 11 girls can do complete work in 3 ¾ days.

Answer 2

1 girl can do the work in = 17 × 5

days

68/3 girls can do the work in =

(17 × 5)/(68/3) days

= (17 × 5 × 3)/68 days

= 15/4 days

= 3 ¾ days

∴ 7 women and 11 girls can do

complete work in 3 ¾ days
