(i) The mechanic can buy an air filter in the following manner:
C — Go to the on-line store using a web browser
B — Enter the key words: air filter, and press the search button
D — Look at the search results and find the right air filter
A — Pay using a credit card
(ii) Two reasons the mechanic might search only websites in the India are :
(f)
(i) One limitation of the coding system described in the scenario is that it lacks differentiation between different levels of late payments. In this system, both a customer who pays after four weeks and a customer who doesn't pay at all are given the same credit rating of 3. It fails to distinguish between a customer who eventually pays but is consistently late and a customer who doesn't pay at all.
(ii) An improved coding system could address this limitation by incorporating more levels of credit ratings to reflect different degrees of payment behavior. Here's a possible improved coding system:
| New Credit Rating | Description |
|---|---|
| 1 | Pays promptly and in full on collecting the car |
| 2 | Pays within two weeks of collecting the car |
| 3 | Pays within four weeks of collecting the car |
| 4 | Pays within six weeks of collecting the car |
| 5 | Pays after six weeks but within two months |
| 6 | Money still owed after two months |

Cell address A4 in a formula means it is a :
Relative cell reference
Reason — Cell address A4 in a formula means it is a Relative cell reference as in this cell referencing technique, the cells are referred to by their relative position in the worksheet.
Cell address $A$4 in a formula means it is a :
Absolute cell reference
Reason — Cell address $A$4 in a formula means it is an Absolute cell reference because the use of $ sign makes the column and row absolute, i.e., the address will not change when the formula is copied to any other cell.
Cell address $A4 in a formula means it is a :
Mixed cell reference
Reason — Cell address $A4 in a formula means it is a Mixed cell reference because the column A is absolute while the row 4 is relative. Thus, when the formula is copied to any other location, the column will remain the same while the row will change.
Cell address A$4 in a formula means it is a :
Mixed cell reference
Reason — Cell address A$4 in a formula means it is a Mixed cell reference because the column A is relative while the row 4 is absolute. Thus, when the formula is copied to any other location, the column will change while the row will remain the same.
How would you refer to the range starting from 1st column, 1st row and spread till 6th column and 3rd row ?
[A1 : F3]
Reason — The cell address of 1st column, 1st row is A1 and the cell address of 6th column and 3rd row is F3. Since a range is specified by giving the addresses of the first cell and the last cell in the range, the range will be referred as [A1 : F3].
The keyboard shortcut for Copy is ................ and for Paste is ................. .
Ctrl + C, Ctrl + V
Reason — The keyboard shortcut for Copy is Ctrl + C and for Paste is Ctrl + V.
When you ................. or ................. , the selected range gets surrounded by a moving border.
Copy, Cut
Reason — When you copy or cut, the selected range gets surrounded by a moving border.
The ............... operation copies data from the source range to target range and erases it from the source range.
Cut and Paste
Reason — The Cut and Paste operation copies data from the source range to target range and erases it from the source range.
If you enter 12 + 24 in a cell, Calc will display ...............
12 + 24
Reason — If we enter 12 + 24 in a cell, Calc will treat it as text and display it as it is i.e., 12 + 24 and not 36.
Address of the cell at 20th column and 30th row is ............... .
T30
Reason — Address of the cell at 20th column and 30th row is T30 because this cell is formed by the intersection of column T and row 30.
The formula in cell A2 is = B2 + C3. On copying this formula to cell C2, the formula in cell C2 will be ................. .
= D2 + E3
Reason — When we copy the formula from cell A2 to cell C2, Calc adjusts the relative cell references in the formula based on the new location. When we copy the original formula "= B2 + C3" to cell C2, Calc will adjust the formula to "= D2 + E3", where it shifts the column references by 2 columns to the right and keeps the row references the same.
Cancel button (x on formula bar) can be used to undo a cell entry after it has been completed.
True
Reason — Cancel button (x on formula bar) can be used to undo a cell entry after it has been completed.
All formulas start with an = sign in Calc.
True
Reason — All formulas start with an = sign in Calc.
If you enter 127A in a cell it will be treated as a number because it starts with a digit.
False
Reason — Any combination of numbers, spaces and non-numeric characters (such as 127A) is treated as text.
A cell entry can be edited either in the cell or in the formula bar.
True
Reason — A cell entry can be edited either in the cell or in the formula bar.
When you clear only the contents of a cell, all the formats and contents are deleted.
False
Reason — When we clear only the contents of a cell, the formats and comments remain intact and only the contents of the cell are deleted.
You cannot open two different workbooks in Calc simultaneously.
False
Reason — We can open two different workbooks in Calc simultaneously.
When a cell containing a formula is moved, the cells referring the moved cell, show an error value.
False
Reason — When a cell containing a formula is moved, Calc automatically adjusts the references in the formula to reflect the new location of the cell. This adjustment is done to ensure that the formula still references the correct cells and data.
Once you copy data on to the clipboard, it can be copied to multiple ranges even after pressing Enter key.
False
Reason — After pasting data from clipboard into a range, the data won't automatically continue to be pasted into additional ranges after pressing Enter.
What is a cell and how is it referred in OOo Calc ?
Cell is a basic unit of worksheet where numbers, text, formulas etc. can be placed. Cell is formed by intersection of a row and a column, which gives a cell a unique address.
For instance, if row 3 is intersected by column F, then the cell formed out of it gets an address F3. Similarly, C5 identifies the cell in column C, row 5.
What do you mean by a range of cells ?
A range of cells is a group of contiguous cells that forms a rectangular area in shape.
A range is specified by giving the addresses of first cell and the last cell of the range. For instance, a range starting from F7 till G14 would be written as F7 : G14 in OOo Calc.

Explain what are the different methods of cell referencing in OOo Calc ?
Cell referencing in OOo Calc are of three types :
Differentiate between mixed referencing and absolute referencing by giving suitable examples.
| Mixed referencing | Absolute referencing |
|---|---|
| Mixed referencing fixes either the row or column while allowing the other to change. | In absolute referencing, both the row and column references are fixed. |
| When a formula with mixed references is copied to another cell, the absolute part of the reference remains fixed while the relative part of the reference changes. | When a formula with absolute references is copied to another cell, the references remain unchanged. |
| For example, C$6 is a mixed reference where column is relative and row is absolute. $C6 is also a mixed reference but here column is absolute and row is relative. | For example, $C$6 is an absolute reference where both row and column are fixed. |
What is the difference between copying and moving a range ?
| Copying a Range | Moving a Range |
|---|---|
| When we copy a range of cells, we create a duplicate copy of the selected cells. | When we move a range of cells, we are relocating the selected cells from their original location to a new location. |
| The original cells remain at their original location, and a copy is placed elsewhere in the worksheet. | The original cells are deleted from their original position and placed at the new location. |
| This is useful when we want to preserve the original data while using a copy for calculations, analysis, or other purposes. | This is useful when we want to reorganize our data within the same worksheet or between worksheets. |
What is the difference between the following commands :
Edit → Delete Contents → Delete all and
Edit → Delete Contents → Text
Edit → Delete Contents → Text and
Edit → Delete Contents → Formats
Edit → Delete Contents → Text and
Edit → Delete Contents → Notes
The Delete All option deletes all content from the selected cell range.
The Text option deletes text only. Formats, formulas, numbers and dates are not affected.
The Text option deletes text only and does not affect formats, formulas, numbers and dates.
The Formats option deletes format attributes applied to cells. All the cell content remains unchanged.
The Text option deletes text only and does not affect formats, formulas, numbers and dates.
The Notes option deletes notes added to cells. All other elements remain unchanged.
Create the following worksheet and save the workbook as WAGES.ods.
(i) Find out the number of days each worker has worked, by subtracting date on which worker was hired from today's date.
(ii) Calculate Gross wages for each worker. The gross wages can be calculated by using the following formula :
Gross wages = No. of days worked * Pay rate
(i) To find out the number of days each worker has worked, follow the given steps:
Step 1 — Select cell C7 and type the formula =$C$3 - B7. Press Enter key. The number of working days will appear in the cell.
The given formula subtracts the date on which the worker was hired from today's date. This gives us the number of days the worker has worked.
Step 2 — With C7 selected, dragging the cell handle from C8 to C12 will copy the formula to the cell range [C8 : C12].
Notice that the formula =$C$3 - B7 will modify itself according to the cell. Cell address $C$3 is an absolute address, so it will not change. But the relative address B7 will change according to the position of the cell.
So, the formula =$C$3 - B8 will be pasted in cell C8, =$C$3 - B9 will be pasted in C9, =$C$3 - B10 will be pasted in cell C10 and so on.
(ii) To calculate the gross wages for each worker, follow the given steps:
Step 1 — Select cell D7 and type the formula =C7*$C$4. Press Enter key. The gross wages of Kushagra will appear in the cell.
The given formula multiplies the number of working days and the pay rate per day.
Step 2 — With D7 selected, dragging the cell handle from D8 to D12 will copy the formula to the cell range [D8 : D12].
Notice that the formula =C7*$C$4 will modify itself according to the cell. Cell address $C$4 is an absolute address, so it will not change. But the relative address C7 will change according to the position of the cell.
So, the formula =C8*$C$4 will be pasted in cell D8, =C9*$C$4 will be pasted in D9, =C10*$C$4 will be pasted in cell D10 and so on.
Create the following worksheet in Ooo Calc.
(i) From the above worksheet find out the average marks for the entire class.
(ii) Now copy the range consisting of the mentioned data (including total, average & class average) to a new location. Find out whether the cell references change or not.
(iii) Now move the original data range to a new location. Find out whether the cell references change or not.
(iv) Again move back the data to its original position and make changes in the marks obtained by students. Notice total, average and class average. What happens ? Why does this happen ?
(i) The average marks for the entire class is 86.
Clear the copied data range (do not touch the 23. original data range).
To clear the copied data range, we follow the given steps:
Step 1 — Select the entire range by clicking on the first cell of the range and dragging the mouse pointer till the last cell of the range.
Step 2 — Right click on the selected range and select 'Clear Contents' from context menu. A 'Delete Contents' window will appear.
Step 3 — Check the check box in front of 'Delete all' option and press OK button.
Create the following worksheet in Ooo Calc :
Below is the created worksheet in Ooo Calc:
From the above created worksheet find out the average marks for the entire class using appropriate formulas.
The average marks for the entire class is 75.2.
Now copy the range consisting of the mentioned entire data (including total, average & class average) to a new location. Find out whether the cell references in formulas change or not.
When we copy the range consisting of the mentioned entire data to a new location, the cell references in the formulas change according to the position of the cells to which they refer.
Now move the original data range (including total, average and class average) to a new location. Find out whether the cell references in formulas change or not.
When we move the original data range to a new location, the cell references in the formulas change according to the position of the cells to which they refer.
Now move back the moved data range to the original position and make changes in the marks obtained by students. Notice total, average and class average. What happens ? Why does this happen ? What is this feature called ?
When we move back the moved data range to the original position and make changes in the marks obtained by students, the Total, Average, and Class Average values will automatically update to reflect the changes. This behavior is known as "relative referencing" i.e., the cell references within the formula are adjusted based on their relative positions when we copy or move the formula to different cells.
When we make changes to the marks obtained by students, the formulas for Total, Average, and Class Average are using relative references to the cells containing the student's marks. As a result, when we move the data range back to the original position, the formulas automatically adjust to reference the correct cells, and the calculations update accordingly.
