### Theory:

Imagine you purchase a few items from a road-side vendor, and the vendor does not provide you with a bill.

But, back at home, your father wants a bill to verify the purchase made.

But, back at home, your father wants a bill to verify the purchase made.

In such a case, you can prepare a bill of your own.

**To prepare a bill, do the following**.

Step 1: Enter the name of the shop.

Step 2: Enter a random bill number (for your reference).

Step 3: Enter the date of purchase.

Step 4: List down all the items that have been bought.

Step 5: Write down the quantity of the items bought.

Step 6: Enter the rates of each item.

Step 7: Calculate the amount to be paid for each item.

Step 8: Calculate the total amount to be paid for the purchase.

Example:

Name of the shop \(=\)

**XYZ Vegetable Mart**Bill Number \(=\) \(120\)

Date of purchase \(=\) \(05-04-2020\)

Item \(1 =\) Onions

Quantity (in kilograms) \(= 2\)

Rate of onions (per kilogram) \(= Rs.50\)

Amount to be paid for the onions \(=\) \(\text{Quantity}\) \(×\) \(\text{Rate}\) \(= 2\) \(×\) \(50 = Rs.100\)

Item \(2 =\) Lemons

Quantity (in kilograms) \(= 3\)

Rate of lemons (per kilogram) \(= Rs.20\)

Amount to be paid for the lemons \(=\) \(\text{Quantity}\) \(×\) \(\text{Rate}\) \(= 3\) \(×\) \(20 = Rs.60\)

Items \(3 =\) Sugar

Quantity (in kilograms) \(= 1\)

Rate of sugar (per kilogram) \(= Rs.60\)

Amount to be paid for sugar \(=\) \(\text{Quantity}\) \(×\) \(\text{Rate}\) \(= 1\) \(×\) \(60 = Rs.60\)

The total amount to be paid for the purchase \(=\) Amount to be paid for the onions \(+\) Amount to be paid for the lemons \(+\) Amount to be paid for sugar

\(= 100 + 60 + 60\)

\(= Rs.220\)

Now, the bill looks like this.

**XYZ Vegetable Mart**

**Bill Number \(=\)**\(120\)

**Date \(=\)**\(05-04-2020\)

S. No | Items | Quantity(in \(kgs\)) | Rate(per \(kg\)) | Amount(in \(Rs.\)) |

1 | Onions | \(2\) | \(50\) | \(100\) |

2 | Lemons | \(3\) | \(20\) | \(60\) |

3 | Sugar | \(1\) | \(60\) | \(60\) |

**Total amount to be paid**\(= Rs.220\)
