A) 6 days
B) 8 days
C) 10 days
D) 13 days
Correct Answer: D
Solution :
(A + B)'s 2 day's work \[=2\left( \frac{1}{12}+\frac{1}{18} \right)=\frac{10}{36}\] Remaining work \[=1-\frac{10}{36}=\frac{26}{36}\] Time taken by B to complete\[\frac{26}{36}\]part of work \[=\frac{26}{36}\times 18=13\]daysYou need to login to perform this action.
