Solution

The correct option is D 60 min
Part of the tank filled by A in 1 min $=\frac { 1 }{ 12 }$

Part of the tank filled by B in 1 min $=\frac { 1 }{ 10 }$.

Part of the tank filled when the three taps are opened together =(112+11016)=5+61060=111060=160

If all the three taps are opened together, then the tank will be filled in 60 minutes.
