A tank has a capacity of 240 litres. A pipe can empty 1/4th of the tank in 5 minutes and another pipe can empty 1/3rd of the tank in 6 minutes. The tank is filled and both the pipes are opened for 3 minutes. How much of the water is now left in the tank?
- 144 liters
- 154 liters
- 164 liters
- 174 liters
- None of these
Explanation
If both pipes are opened for 3 minutes then water taken out=(12l*3)+(40/3l*3)=36l+40l=76l
Water left in tank=240l-76l=164l
