Answers

Step 1- Open Libreoffice calc and Enter the data as shown in the question

	A	B	C	D	E	F	G
1	S. No.	Year	Subject 1	Subject 2	Subject 3	Subject 4	Average
2	1		243	234	123	354	=average(C2:F2)
3	2		532	367	893	265
4	3		432	256	782	165
5	4		432	545	645	642
6	5		234	765	934	278
7		Total

Step 2- After entring the data type the formula =average(C2:F2) into G2 cell and <Press Enter>. And Select G2 cell and drag so you will all the values. See the table given below

	A	B	C	D	E	F	G
1	S. No.	Year	Subject 1	Subject 2	Subject 3	Subject 4	Average
2	1		243	234	123	354	238.5
3	2		532	367	893	265	514.25
4	3		432	256	782	165	408.75
5	4		432	545	645	642	566
6	5		234	765	934	278	552.75
7		Total	=sum(C2:C6)

Step 3- Same as the above type total formula=sum(C2:C6) into cell C7 and press enter.And select C7 than drag right side so you will get total of subject1, subject2, subject3 and subject 4.See the table given below

	A	B	C	D	E	F	G
1	S. No.	Year	Subject 1	Subject 2	Subject 3	Subject 4	Average
2	1		243	234	123	354	238.5
3	2		532	367	893	265	514.25
4	3		432	256	782	165	408.75
5	4		432	545	645	642	566
6	5		234	765	934	278	552.75
7		Total	1873	2167	3377	1704

Step 4- To print the above table Go To File>Select print> then print dialog box will appear on the screen.

Question 2. Create a table in LibreOffice Writer as shown below

Roll No.	Name	Marks In Physics	Marks in Chemistry	Total Marks
1	Arohi	76	78
2	Ananya	78	56
3	Sumit	89	78
4	Amit	56	56
5	Vivan	78	89
6	Naina	98	67

Do the Following

1. In the total marks column, entries should be calculated using formulas and it is the sum of marks in physics and marks in chemistry.

2. Insert a row at the end of the table ans also find grand total using formula.

3. Sort the table based on the total marks

Answers

Step 1- Firstly open LibreOffice Writer application

Step 2- To create table do the following steps——- GO to Tbale Menu—–>Select Insert table then insert table dialog box will appear on your computer screen.In this box write number of column is 5 and row is 7 & click on insert button .

Step 3- Table will appear on the screen. Enter the column headings that are gien on question like- Roll number,Name,Marks etc.

Step 4- Solution (a)-

To make formula entry in Total Marks column, click on Total marks column and Go to Table menu—>select edit formula or press F2. Then type the folllowing formula=sum(<c2:d2>) and click on apply button

Roll No.	Name	Marks In Physics	Marks in Chemistry	Total Marks
1	Arohi	76	78	=sum(<c2:D2>)
2	Ananya	78	56
3	Sumit	89	78
4	Amit	56	56
5	Vivan	78	89
6	Naina	98	67

Same as you can type formula in other remaining rows and display the output.

Roll No.	Name	Marks In Physics	Marks in Chemistry	Total Marks
1	Arohi	76	78	154
2	Ananya	78	56	134
3	Sumit	89	78	167
4	Amit	56	56	112
5	Vivan	78	89	167
6	Naina	98	67	165

Step 5- Solution (b)-

To insert a new row at the end of the table, Click on Last Row of a table, Go To table menu—>Select Insert—>Rows Below

 

Then table row will be inserted into the existing table. In this Row find the Grand Total and type the following formula=sum(<E2:E7>)

Roll No.	Name	Marks In Physics	Marks in Chemistry	Total Marks
1	Arohi	76	78	154
2	Ananya	78	56	134
3	Sumit	89	78	167
4	Amit	56	56	112
5	Vivan	78	89	167
6	Naina	98	67	165
			Grand Total	=sum(<E2:E7>)

Question 3:  Type the following data in spreadsheet ans save it

A	B	C	D
X	Y
370	12
98.5	78
7452	8
142	78
365	85.5
156	45
14.5	950

Do The following

1. 1. 1. Complete Column C for finding product x*y

      2. Find sum of X column at the end of the data

      3. Find sum of Y column at the end of the data

1. Find sum of X*Y  column at the end iof the data

2. Find Sum of X^2

3. Find Sum of Y^2

Answer–

Step 1- Firstly Open Libreoffice Calc and enter the data as shown in the given question Watch video for practical

Step 2-

Solution (1)- To Complete clumn C for finding product x*y, Type formula=A2*B2 in column C2 & select Fill by drag and drop.

A	B	C	D
X	Y	x*y
370	12	=A2*B2
98.5	78
7452	8
142	78
365	85.5
156	45
14.5	950

Step 3- Solution (2)

To find sum of X column at the end of data type the formula=sum(A2:A9) into the A10 cell

A	B	C	D
X	Y
370	12
98.5	78
7452	8
142	78
365	85.5
156	45
14.5	950
=sum(A2:A9)

Step4 – Solution (3)

Type the fomula= sum(B2:B9) into the B10 cell & press enter

Solution (4)

Type the fomula= sum(C2:C9) into the C10 cell & press enter

Solution (5)

Find the sum of X^2 by apply the formula=A^2 (^ sign present in number 6 key)

Type the fomula= sum(D2:C9) into the B10 cell & press enter

Solution (6)

Find sum of Y^2 by apply the formula=B^2

Type the fomula= sum(E2:E9) into the E10 cell & press enter
