A) 2400
B) 4500
C) 1200
D) 7200
Correct Answer: D
Solution :
Let the capacity of the tank = x litres According to the question, Quantity of water emptied by the leak in 1 h \[=\frac{x}{10}\text{L}\] Quantity of water filled by the tap in 1 h = 240 L According to the question, \[\frac{x}{10}-\frac{x}{15}=240\] \[\Rightarrow \] \[\frac{3x-2x}{30}=240\] \[\Rightarrow \] \[\frac{x}{30}=240\] \[\therefore \] \[x=240\times 30=7200\,\,\text{L}\]You need to login to perform this action.
