A) 8 h
B) 7 h
C) \[2\frac{1}{3}\,h\]
D) 14 h
Correct Answer: D
Solution :
Part of the tank tilled by the pump in \[1\,\,h=\frac{1}{2}\] Because of leak part of the tank filled by the pump in \[1\,\,h=\frac{3}{7}\] \[\therefore \] Part of the tank emptied by the leak in 1 h \[=\frac{1}{2}-\frac{3}{7}=\frac{7-6}{14}=\frac{1}{14}\] Hence, the leak will empty the tanks in 14 h.You need to login to perform this action.
