1. (x + 4y)>1 2. x> -4y 3. None of these
Explanation!!!
A water tank of 3600 cu m capacity is being filled with water. The delivery of pump discharging the tank is 20% more than the delivery of the pump filling the same tank. As a result, 12 mins more time is needed to fill the tank to discharge it. Determine the delivery of the pump discharging the tank.
1) 40 m3/min 2) 50m3/min 3) 60m3/min 4) 80m3/min 5) 70 m3/min
Explain. Don't have answer.
