Problem Analysis

To determine if there will be enough water in the tank on Thursday, we need to calculate the amount of water remaining in the tank each day. We know that the tank initially holds 1000 liters of water, and each day 600 liters are consumed. Additionally, each night half of the remaining water in the tank is refilled.

Calculation

Let's calculate the amount of water in the tank each day, starting from Monday morning:

- Monday morning: The tank is full with 1000 liters. - Monday evening: 600 liters are consumed, leaving 400 liters in the tank. - Tuesday morning: Half of the remaining water (200 liters) is refilled, bringing the total to 600 liters. - Tuesday evening: 600 liters are consumed, leaving 0 liters in the tank. - Wednesday morning: Half of the remaining water (0 liters) is refilled, bringing the total to 0 liters. - Wednesday evening: 600 liters are consumed, leaving -600 liters in the tank. - Thursday morning: Half of the remaining water (-600 liters) is refilled, bringing the total to -300 liters.

Conclusion

Based on the calculations, there will not be enough water in the tank on Thursday morning. The tank will have a deficit of 300 liters of water.
