    Water Tank Puzzle......

    Hi Friends,

    Water flows into a tank at a rate of 1 gallon per second.

    Water leaves the tank at a rate of 1 gallon per second for each 100 gallons in the tank.


    The tank is initially empty.

    Then guys....

    How long will it take for the tank to fill with 50 gallons of water?

    Thanks & Regards,
    Riju
