Remaining Alcohol after 40% of the alcohol evaporates will be = 1800 - 1800 * 0.4 = 1080
Water remains as it is, so the total remaining liquid in the tub is = 1080 + 920 = 2000
So, percentage of water is = (920 / 2000) * 100 = 46 %
Answer is C

\(40\)% of alcohol = \(1800 \times \frac{40}{100}= 720\) liters
Alcohol that remains after evaporation is \(1800-720=1080\) liters
The amount of water available = \(920\) liters
Total amount of water and alcohol remaining = \(1080+920=2000\) liters
Percentage of water \(= \frac{920}{2000} \times 100 = 46\)%
The answer is C
