Answer : The amount of salt present in the tank initially are, 50 kg
Explanation : Given,
Mass of salt in the tank = 50 kg
Mass of water in the tank = 1000 L
Rate of flow of water in the tank = 6 L/min
Rate of flow of solution in the tank = 3 L/min
Now we have to determine the amount of salt present in the tank initially.
As per question, there are 50 kg of salt present in the tank initially in 1000 L of water.
Thus, the amount of salt present in the tank initially are, 50 kg
