    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 \[=\frac{26}{36}\times 18=13\]days
