###### 3. A 100L mixing tank is initially filled with 20 g/1 sugar solution. As more sugar solution is pumped in, & tap is opened, draining some of the tank Sugar water enters the tank at the rate of 10 L/ht; but the level of sweetness is constantly increasing; so that the solution has t2 g/L of sugar after t hours The solutions are mixed instantly and the amount drained is 20 L/hr Find the concentration of the sugar in the mixing tank and prove mathematically what the concentration is equal to as
