To calculate the amount due to the vendor per day, we first need to determine the total amount of milk supplied by the vendor in a day.
In the morning, the vendor supplies 32 liters of milk, and in the evening, he supplies 68 liters. So, the total milk supplied in a day is:
- 32 liters (morning) + 68 liters (evening) = 100 liters
Next, we find out the cost of the total milk supplied. The cost of milk is Rs 15 per liter. Therefore, the total cost for the 100 liters of milk is:
- 100 liters × Rs 15/liter = Rs 1500
Thus, the total amount due to the vendor per day for the milk supplied to the hotel is Rs 1500.
