1. 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
2. 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 \(= Rs.550\)
