Answer 3

Calculating Water Flow into the Tank

To calculate the amount of water that will be filled into the tank in 50 minutes, we can use the following formula:

Water filled into the tank = (Water inflow rate - Water outflow rate) * Time

Given: - Water inflow rate = 35 liters per minute - Water outflow rate = 10 liters per minute - Time = 50 minutes

Using the formula, we can calculate the amount of water that will be filled into the tank.

Calculation

Water filled into the tank = (35 - 10) * 50

Now, let's calculate the result.

Water filled into the tank = (35 - 10) * 50 = 25 * 50 = 1250 liters

So, the amount of water that will be filled into the tank in 50 minutes is 1250 liters.

Therefore, the correct answer is 1250 liters (option Д).
