    B)  12  

    C)  8                    

    D)         14

    Correct Answer: B

    Solution :

     If the third tap empties the tanking hours then, 12             \[=\frac{10\times 15\times x}{10x+15x-10\times 15}\] or,        \[12=\frac{150x}{25x-150}\] or,\[300x-1800=150x\] or, \[150x=1800\] \[\therefore \]\[x=\frac{1800}{150}\] \[=12\]hours
