A) \[2\frac{2}{5}\text{days}\]
B) \[2\frac{2}{11}\text{days}\]
C) \[3\frac{3}{17}\text{days}\]
D) \[3\frac{2}{5}\text{days}\]
Correct Answer: A
Solution :
(A + B)'s 1 day's work \[=\frac{1}{6}+\frac{1}{8}=\frac{7}{24}\] C'S 1 day's work \[=\frac{7}{24}\] \[\therefore \] (B + Q)'s 1 day's work \[=\frac{1}{8}+\frac{7}{24}=\frac{5}{12}\] \[\therefore \] B and C together will complete the work in \[\frac{12}{5}=2\frac{2}{5}\,\text{days}\]You need to login to perform this action.
