**Verify the correctness of the following bill**.

**ABC Store**,

**Chennai**

Bill Number \(=\) \(25\)

Date \(=\) \(06-06-2020\)

S. No. | Items | Quantity(in nos.) | Rate(per item) | Amount (in \(Rs.\)) |

1 | Bag | \(2\) | \(500\) | \(1000\) |

2 | Bottle | \(3\) | \(25\) | \(75\) |

3 | Notepad | \(5\) | \(50\) | \(250\) |

Total amount to be paid \(=\) \(Rs.1325\)

Solution:

Item \(1 =\) Bag

Quantity (in numbers) \(= 2\)

Rate (per item) \(= Rs.500\)

Amount to be paid for the bags \(=\) \(\text{Quantity}\) \(×\) \(\text{Rate}\) \(= 2\) \(×\) \(500 = Rs.1000\)

**Verdict**: Verified

Item \(2 =\) Bottle

Quantity (in numbers) \(= 3\)

Rate (per item) \(= Rs.25\)

Amount to be paid for the bottles \(=\) \(\text{Quantity}\) \(×\) \(\text{Rate}\) \(= 3\) \(×\) \(25 = Rs.75\)

**Verdict**: Verified

Item \(3 =\) Notepads

Quantity (in numbers) \(= 5\)

Rate (per item) \(= Rs.50\)

Amount to be paid for the notepad \(=\) \(\text{Quantity}\) \(×\) \(\text{Rate}\) \(= 5\) \(×\) \(50\) \(= Rs.250\)

**Verdict**: Verified

Total amount to be paid \(=\) Amount to be paid for Item \(1\) \(+\) Amount to be paid for Item \(2\) \(+\) Amount to be paid for Item \(3\)

\(=\) Amount to be paid for the bags \(+\) Amount to be paid for the bottles \(+\) Amount to be paid for the notepads

\(= 1000 + 75 + 250\)

\(= Rs.1325\)

**Verdict**: Verified

**Prepare a bill for the following set of items**.

\(4\) kilograms of apples worth \(Rs.60\) per kilogram.

\(3\) kilograms of oranges worth \(Rs.50\) per kilogram.

\(4\) kilograms of mangoes worth \(Rs.40\) per kilogram.

Solution:

Item \(1\) \(=\) Apples

Quantity (in kilograms) \(= 4\)

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

Amount to be paid for the apples \(=\) \(\text{Quantity}\) \(×\) \(\text{Rate}\) \(= 4\) \(×\) \(60\) \(= Rs. 240\)

Item \(2 =\) Oranges

Quantity (in kilograms) \(= 3\)

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

Amount to be paid for the oranges \(=\) \(\text{Quantity}\) \(×\) \(\text{Rate}\) \(= 3\) \(×\) \(50\) \(= Rs.150\)

Item \(3\) = Mangoes

Quantity (in kilograms) \(= 4\)

Rate (per kilogram) \(= 40\)

Amount to be paid for the oranges \(=\) \(\text{Quantity}\) \(×\) \(\text{Rate}\) \(= 4\) \(×\) \(40 = Rs.160\)

The total amount to be paid \(=\) Amount to be paid for Item \(1 +\) Amount to be paid for Item \(2 +\) Amount to be paid for Item \(3\)

\(= 240 + 150 + 160\)

\(= Rs.550\)

Now, the bill will look like the following.

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

1 | Apples | \(4\) | \(60\) | \(240\) |

2 | Oranges | \(3\) | \(50\) | \(150\) |

3 | Mangoes | \(4\) | \(40\) | \(160\) |

Total amount to be paid \(= Rs.550\)
