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 40 m above the ground, and the efficiency of the pump is 30%, how much electric power is consumed by the pump?
(Take `g = 10 m s^(-2)`)

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