Case-Study Based Questions

Question 1

Formula is an expression consisting of numeric values and operators. You can perform arithmetical operations on a set of values using formulae. It is important to know that all MS Excel formulae must begin with an equal sign (=) followed by an expression. The formulae used to perform different tasks are shown below:

(a) Task (1)

Write the result of the MS Excel formulae. Spreadsheet Introduction, Understanding Computer Studies Solutions ICSE Class 7.

(b) Task (2)

Write the result of the MS Excel formulae. Spreadsheet Introduction, Understanding Computer Studies Solutions ICSE Class 7.

(c) Task (3)

Write the result of the MS Excel formulae. Spreadsheet Introduction, Understanding Computer Studies Solutions ICSE Class 7.

(d) Task (4)

Write the result of the MS Excel formulae. Spreadsheet Introduction, Understanding Computer Studies Solutions ICSE Class 7.

The space is provided alongside to write the result of the formulae for each of the above tasks.

Answer

(a) 33
Working — A2 = 30, B2 = 12, C2 = 4
Formula = A2 + B2 / C2
= 30 + 12 / 4
= 30 + 3 = 33

(b) 1.5
Working — A6 = 12, B6 = 8
Formula = A6/B6
= 12 / 8 = 1.5

(c) 10
Working — A4 = 45, B4 = 9, C4 = 2
Formula = A4 / B4 * C4
= 45 / 9 * 2
= 5 * 2 = 10

(d) 15
Working — A8 = 15, B8 = 3, C8 = 10
Formula = A8 / B8 + C8
= 15 / 3 + 10
= 5 + 10 = 15

Short Answer Questions

Question 1

What is a spreadsheet?

Answer

Spreadsheet is a large sheet which contains data and information. It is a grid of rows and columns and is also called a worksheet. A computer spreadsheet is also known as Electronic spreadsheet. It is used for analyzing and evaluating data represented in tabular form.

Question 2

What is the significance of Undo and Redo buttons?

Answer

The Undo feature can quickly correct mistakes that we make in a worksheet. When we want to reverse our last action in a worksheet, we click on 'Undo' button.

The Redo button lets us perform the previous task by using 'Undo'. It changes in response to whatever action we just took. The 'Redo' button becomes active whenever we use 'Undo' button.

Question 3

Define the following terms

  1. Worksheet
  2. Workbook
  3. Cell
  4. Active cell
  5. Formula bar

Answer

Worksheet — Each page of a workbook is called worksheet. The active worksheet is displayed in the window. The default worksheets are sheet 1, sheet 2, sheet 3.

Workbook — Workbook is a file, which contains a number of worksheets. By default, three worksheets are present in a workbook. You can add or remove worksheets from a workbook as per the requirement.

Cell — A cell is the smallest unit of the worksheet, which is formed at the intersection of a row and a column. Each cell has its own cell address for reference. The address of the cell consists of the column letter followed by the row number.

For example, Cell F4 means column F and row 4.

Active cell — The cell in which cell pointer is located in a worksheet is the active cell. It has a dark boundary around it. It is also known as the cell. We can move cell pointer to make any other cell active either with the help of arrow keys of the keyboard or by using mouse.

Formula bar — It is used to write formulae to perform different mathematical and logical tasks.

Long Answer Questions

Question 1

What are the advantages of an electronic spreadsheet?

Answer

The advantages of an electronic spreadsheet are as follows:

  1. By default, it creates the arrangement of data into columns and rows called cells.
  2. The data that is input into the spreadsheet can be either in the form of numbers, strings or formulae.
  3. The inbuilt programs allow you to change the appearance of the spreadsheet, including the column width, row height, font color and color of the spreadsheet very easily.
  4. You can choose to work with or print a whole spreadsheet or specify a particular area, called a range.
  5. MS Excel spreadsheet enhances to analyze large amounts of data with the help of powerful tools.

Question 2

Enlist the features of an electronic spreadsheet.

Answer

The features of an electronic spreadsheet are as follows:

  1. MS Excel is easy to learn and thus, it does not require any specialised training programme.
  2. MS Excel basically provides an electronic spreadsheet where all the calculations can be done automatically through built-in programs.
  3. Spreadsheets are required mainly for tabulation of data. It minimizes manual work and provides high degree of accuracy in results.
  4. It also provides multiple copies of the spreadsheets.
  5. To perfrom the basic Mathematical operations such as addition, subtraction, multiplication or division to produce numeric results, we use arithmetic operators like +,-,*,/.
  6. It presents the information in the form of charts and graphics.
  7. MS Excel is able to sort the data in either ascending or descending order very easily.
  8. MS Excel also allows you to add password to a workbook. It avoids any kind of unauthorised access to the data.

Question 4

What are the different types of data used in MS Excel? Explain.

Answer

Three frequently used data types in MS Excel are:

  1. Number — This data represents numeric values including both integers and real numbers. They take part in all arithmetical operations such as addition, subtraction, multiplication, division, etc. By default, the numbers are right aligned.
    For example, 1500, -345, 645.67, -76.50, etc.
  2. String — The String type data are also known as text data in MS Excel. They contain alphanumeric characters (i.e. uppercase letters/lowercase letters, digits and special symbols). They don't take part in arithmetical operations. By default, the strings are left aligned.
    For example, Name, Marks, Total, Product_Name, Pay2021, etc.
  3. Formula — It is an expression consisting of numeric values and operators. You can perform all arithmetical operations on a set of values using formulae. All Excel formulae must begin with an equal sign (=) followed by an expression. Some examples are as illustrated below:
    1. To find the sum of two values say, 10 and 20
      Formula: =10 + 20
    2. To add the cell values from A1 to A3
      Formula: =A1 + A2 + A3
    3. To add the cell value A3 with the product of cell values A1 and A2
      Formula: =A1 * A2 + A3

Question 5

How will you perform simple addition and multiplication of numbers in a cell of a worksheet? Explain.

Answer

Steps to perform simple addition in a cell of a worksheet:

Step 1: Select the cell (say, B2) where you want to perform the addition.

Step 2: Type the required expression, for example =45 + 32

Step 3: Press Enter key. The result is shown in the selected cell. (For our example, B2 will show the result as 77).

Steps to perform multiplication in a cell of a worksheet:

Step 1: Select the cell (say, C2) where you want to perform the multiplication.

Step 2: Type the required expression, for example =12*10*5

Step 3: Press Enter key. The result is shown in the selected cell. (For our example, C2 will show the result as 600).

Question 6

Using the concept of formula in MS Excel, write down all the steps:

(a) to calculate the product of values available in the cells A2, B2, C2 and D2

(b) to find the result when sum of cells A4 and A5 are divided by A6

Answer

(a) Steps to calculate the product of values available in the cells A2, B2, C2 and D2:

Step 1: Select the cell (say, E2), where you want to get the resulting value.

Step 2: Type equal sign (=) in the cell (cell E2 as per our example) and write the formula =A2*B2*C2*D2. Cells A2 to D2 will get highlighted.

Step 3: Press Enter key. The result is displayed in the selected cell.

(b) Steps to find the result when sum of cells A4 and A5 are divided by A6:

Step 1: Select the cell (say, A7), where you want to get the resulting value.

Step 2: Type equal sign (=) in the cell (cell A7 as per our example) and write the formula =SUM(A4,A5)/A6. Cells A4 to A6 will get highlighted.

Step 3: Press Enter key. The result is displayed in the selected cell.
