Let's solve the problem step-by-step to determine how much water the mineral water plant can prepare in 30 days.
1. Determine the amount of water prepared per hour:
- According to the given information, the plant prepares 750 liters of water in one hour.
2. Calculate the amount of water prepared in one day:
- There are 24 hours in one day.
- Therefore, the amount of water prepared in one day can be calculated by multiplying the amount of water prepared per hour by the number of hours in a day.
- Amount of water prepared in one day = 750 liters/hour 24 hours/day = 18,000 liters/day
3. Calculate the total amount of water prepared in 30 days:
- Now we need to determine how much water the plant can prepare in 30 days.
- This can be done by multiplying the amount of water prepared in one day by the number of days (30 days).
- Total amount of water prepared in 30 days = 18,000 liters/day 30 days = 540,000 liters
Therefore, the mineral water plant can prepare 540,000 liters of water in 30 days. Among the given options, (a) 540000 is the correct answer.
