A motor can pump up water to fill a tank of volume `500 m^3` in 25 minutes, which is placed at a height of 20m. If efficiency of the motor is 40% , calculate the power of the motor.

A pump on the ground floor of a building can pump up water to fill a tank of volume 30 m^3 in 15 min. If the tank is 60 m above the ground, and the efficiency of the pump is 40%, how much electric power is consumed by the pump? (Take g = 10 m s^(-2) )

A motor is used to lift water from a well of depth 10m and to fill a water tank of volume 30m^(3) in 10 minutes. The tank is at a height of 20m above ground. If 20% of energy is wasted, the power of the motor is
