A vendor supplies `105` litres of milk to a hotel in the morning and `85` litres of milk in the evening . If the milk costs Rs. `20` per litre then how much money is due to the vendor per day ?

Options

A. Rs. `3500`
B. Rs. `4200`
C. Rs. `3950`
D. Rs. `3800`

Answer

To find out how much money is due to the vendor per day, we will follow these steps:

### Step 1: Calculate the total amount of milk supplied in a day.
The vendor supplies milk in two parts:
- In the morning: 105 litres
- In the evening: 85 litres

To find the total amount of milk supplied in a day, we add the two quantities together:

\[ \text{Total Milk} = \text{Morning Milk} + \text{Evening Milk} \]
\[ \text{Total Milk} = 105 \, \text{litres} + 85 \, \text{litres} \]
\[ \text{Total Milk} = 190 \, \text{litres} \]

### Step 2: Calculate the total cost of the milk supplied.
The cost of milk is given as Rs. 20 per litre. To find the total cost, we multiply the total amount of milk by the cost per litre:

\[ \text{Total Cost} = \text{Total Milk} \times \text{Cost per litre} \]
\[ \text{Total Cost} = 190 \, \text{litres} \times 20 \, \text{Rs/litre} \]
\[ \text{Total Cost} = 3800 \, \text{Rs} \]

### Conclusion:
The total amount of money due to the vendor per day is Rs. 3800.
