Quantity of milk supplied in the morning = 32 litres

Quantity of milk supplied in the evening = 68 litres

Cost of milk per litre = Rs. 45

Total cost per day = 45 × (32 + 68)

                             = 45 × 100

                             = Rs. 4500

Therefore Rs. 4500 money is due to the vendor per day.
