A) 56 days
B) 48 days
C) 36 days
D) 164 days
Correct Answer: B
Solution :
Let B alone can complete the work = x days \[\therefore \](A + B)'s 1 day work\[=\frac{1}{24}+\frac{1}{x}=\frac{1}{16}\] \[\Rightarrow \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\frac{1}{x}=\frac{1}{16}-\frac{1}{24}=\frac{1}{48}\] Hence, B alone completes the work in 48 days.You need to login to perform this action.
