A) 10 days
B) 12 days
C) 13 days
D) 15 days
Correct Answer: D
Solution :
5 men?s 1 day?s work \[=\frac{1}{19}\] 1 man?s 1 day?s work\[=\frac{1}{95}\] 9 women?s 1 day?s work\[=\frac{1}{19}\] 1 women?s 1 day?s work\[=\frac{1}{171}\] (3 men + 6 women?s) 1 day?s work \[=\left( \frac{3}{95}+\frac{6}{171} \right)=\frac{(27+30)}{855}=\frac{57}{855}=\frac{1}{15}\] \[\therefore \]3 men and 6 women can finish the work in 15 days.
