B) 21 days
C) 24 days
D) 27 days
Correct Answer: A
Solution :
Work of (1 ma n + 1 women + 1 boy) for 1 day\[=\frac{1}{3}\] \[\therefore \] Work of 1 man for 1 day\[=\frac{1}{6}\] and work of 1 boy for 1 day\[=\frac{1}{18}\] \[\therefore \]Work of 1 women for 1 day\[=\frac{1}{3}-\frac{1}{6}-\frac{1}{18}=\frac{1}{9}\] Hence, woman alone will complete the work in 9 days.You need to login to perform this action.
