A water cooler is installed in a school with a tap at the bottom that can empty the filled water cooler in 45 minutes. A pipe is connected to the top of the cooler that can fill the empty water cooler in 30 minutes. When the water cooler was half-empty, the top pipe was opened to fill the cooler. Simultaneously, some kids dispensed water from the cooler for 9 minutes. In how much time will the water cooler be completely filled?
A water cooler is filled when it is half empty with the help of a pipe which can fill the whole cooler in 50/3 minutes. There is an outlet tap at the bottom of the cooler which can empty the tank in 25 minutes. When the inlet pipe is started, a person comes and takes out the water from that tap for 1 minute then after a gap of 2 minutes another person comes and takes out the water for 1 minute and this process goes on. In how much time cooler will be completely full?
