Marks: +1, -0

10 men or 15 women can complete a work in 30 days. In how many days can 15 men and 27 women complete the work?

Solution:

Given,

15 {W} ≡ 10 {M}

can complete the work in 30 days.

∴ \;\; 27 {W} ≡ \;{10 × 27}/{15} {M} ≡ 18 {M}

∴ 15 {M}+27 {W} ≡ 15 {M}+18 {M} ≡ 33 {M}

\;\text " Since, "\; 10 {M} \;\text " can complete the work in "\;

30 \;\text " days. "\;

∴ 33 {M} \;\text " can complete the work in "\;

\;\;\; =\;{30 × 10}/{33} \;\text " days "\;=\;{300}/{33}=9 \;{1}/{11} \;\text " days "\;
