After 7 minutes both the tanks will have the same amount of water.
Step-by-step explanation:
The water is filling in a tank at the rate of 75 L/mins from an initial 550 L of water and water is removing from another tank at the same rate from the initial 1600 L of water.
Let us assume that the same amount of water will be there in both the tanks after t minutes.
Therefore, 550 + 75t = 1600 - 75t
⇒ 150t = 1050
⇒ t = 7
Therefore, after 7 minutes both the tanks will have the same amount of water. (Answer)
