A) 111 days
B) 12 3 days
C) 131 days
D) 164 days

Solution :
(A + B)?s 1 day's work \[=\frac{1}{5}\] A's 1 day's work \[=\frac{1}{8}\] \[\therefore \] B's 1 day's work \[=\frac{1}{5}-\frac{1}{8}\] \[=\frac{8-5}{40}=\frac{3}{40}\] \[\therefore \] B alone will complete the work in \[\frac{40}{3}\]\[=13\frac{1}{3}\,\text{days}\text{.}\]You need to login to perform this action.
