A pump draws water from a tank which is at $2.5\; m$ down from outlet and issues it from the end of a hose which the water is drawn. The cross sectional area is $10\; cm ^{2}$, and the water leaves the end of the hose at a speed of $5\; m / s$. What is the rate at which the pump is working ?
  • A$100 $
  • B$185 $
  • C$96 $
  • D$200 $
