Accepted Answer

(a)(i) The mechanic can change the cost of an air filter by editing cell C7.(ii) The mechanic should highlight the cell and enter the new cost.(b) The two cells that should change automatically when the cost of an air filter is changed are C10 and C11.(c)Tick three boxesPrinterWebsite address✓IdeaFormula✓Picture✓Word processor(d)Tick three boxesA lesson on percentages so the mechanic can calculate VATAn index to help the mechanic find the information needed✓A road map to help the mechanic find the route to the parts warehouseA tutorial guide to help the mechanic use the spreadsheet✓A dictionary that helps the mechanic understand the meaning of wordsA search engine to help the mechanic find the information needed✓(e)(i) The mechanic can buy an air filter in the following manner:C — Go to the on-line store using a web browserB — Enter the key words: air filter, and press the search buttonD — Look at the search results and find the right air filterA — Pay using a credit card(ii) Two reasons the mechanic might search only websites in the India are :Local Compatibility — Searching for websites within India ensures that the mechanic finds options that are specifically designed to fit vehicles commonly used in the Indian market.Get the best price and faster delivery — By focusing on websites within India, the mechanic will avoid import duties so he can get the air filter at the best price. Also shipping time from suppliers within India will be less compared to overseas suppliers.(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 RatingDescription1Pays promptly and in full on collecting the car2Pays within two weeks of collecting the car3Pays within four weeks of collecting the car4Pays within six weeks of collecting the car5Pays after six weeks but within two months6Money still owed after two months

Question 5

Question 7Cell address $A$4 in a formula means it is a :Mixed cell referenceAbsolute cell referenceRelative cell referenceAll the above.

Accepted Answer

Absolute cell referenceReason — 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.

Question 6

Question 8Cell address $A4 in a formula means it is a :Mixed cell referenceAbsolute cell referenceRelative cell referenceAll the above.

Accepted Answer

Mixed cell referenceReason — 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.

Question 7

Question 9Cell address A$4 in a formula means it is a :Mixed cell referenceAbsolute cell referenceRelative cell referenceNone of the above

Accepted Answer

Mixed cell referenceReason — 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.

Question 12

Question 6What will happen to the contents of the destination cell if you copy the contents of the source cell into the destination cell ?

Accepted Answer

If we copy the contents of the source cell and paste them into the destination cell, the contents of the destination cell will be replaced by the contents of the source cell. The original contents of the destination cell will be overwritten with the copied data from the source cell.

Question 13

Question 12What are the rules to be followed while entering the following in OOo Calc ?(i) numbers(ii) text(iii) formulas

Accepted Answer

The rules to be followed while entering the following in OOo Calc are as follows:(i) Numbers — A number can contain only the following characters :0 1 2 3 4 5 6 7 8 9 + - ( ) , / $ % . E e(ii) Text — Text is any combination of numbers, spaces, and non-numeric characters.(iii) Formulas — A formula begins with an '=' sign and can contain values (entries that can be used for calculations), operators (e.g., +, /, *) and cell addresses (e.g., C9, B14).

Question 14

Question 13Explain what are the different methods of cell referencing in OOo Calc ?

Accepted Answer

Cell referencing in OOo Calc are of three types :Relative referencing — Cell referencing in which the cells are referred by their relative position in the worksheet — relative to a particular cell is known as Relative referencing. For example, A23, BZ15 etc.Absolute referencing — Cell referencing in which the cells are referred by their fixed position (absolute position) in the worksheet is known as Absolute referencing. For example, $A$23, $Z$15 etc.Mixed Referencing — Combination of relative and absolute referencing is called mixed referencing. For example, A$23, $Z15 etc.

Question 15

Question 15Differentiate between mixed referencing and absolute referencing by giving suitable examples.

Accepted Answer

Mixed referencingAbsolute referencingMixed 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.

Question 16

Question 16What is the difference between copying and moving a range ?

Accepted Answer

Copying a RangeMoving a RangeWhen 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.

Question 17

Question 17What is the difference between the following commands :Edit → Delete Contents → Delete all andEdit → Delete Contents → TextEdit → Delete Contents → Text andEdit → Delete Contents → FormatsEdit → Delete Contents → Text andEdit → Delete Contents → Notes

Accepted Answer

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.

Question 18

Question 18Create 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

Accepted Answer

(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.

Question 19

Question 19Create 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.
