Answer – Types of image tools are :
• Selection Tools – The Select tool is used to select images or objects on the canvas. It allows users to move, resize, rotate, or group images and drawings easily.
• Drawing Tools – Drawing tools include Line tool, Arrow tool, Rectangle, Ellipse, Curve, Polygon, and Text tool. These tools are used to draw shapes, curves, lines, and insert text within the image area.
• Image Manipulation Tools – These tools are used to modify images. Cropping tool removes unwanted parts, resizing handles change image size, rotate tool changes orientation, and brightness/contrast tools adjust image clarity.
• Color and Filter Tools – Color tools are used to recolor images, convert them into grayscale or black and white, while filters apply special effects such as blur or artistic styles.
• Image File Management Tools – Images can be inserted as linked or embedded files. Linked images keep the file size small, while embedded images are stored inside the document. Common image formats include JPEG, PNG, GIF, and BMP.
OR
Explain various types of styles.
Answer – Types of styles are :
• Paragraph Styles – Paragraph styles are used to format a whole paragraph at once. They control alignment, indentation, line spacing, borders, and spacing before or after a paragraph. Example: Making all headings bold, centered, and properly spaced.
• Character Styles – Character styles are applied to selected text such as words or phrases. They change font type, size, color, and apply effects like bold or italics without affecting the entire paragraph. Example: Highlighting an important word in blue.
• Frame Styles – Frame styles are used to format frames or text boxes containing text or images. They control borders, background color, spacing, and position on the page. Example: Adding a border to an image caption box.
• Page Styles – Page styles define the layout of a page. They control margins, headers, footers, page orientation, columns, and background. Example: Using a two-column layout on selected pages.
• List Styles – List styles format bulleted or numbered lists. They control bullet symbols, numbering style, and indentation to make lists clear and organized. Example: Using Roman numerals for main points
2. What is goal seek? Write steps to use it.
Answer – Goal Seek is a What-If Analysis tool in spreadsheet software such as MS Excel. It is used to find the required input value in one cell when the desired result (target value) of a formula is already known. Goal Seek works by automatically changing one input cell until the formula cell reaches the specified goal. It is useful in situations like finding required sales for a given profit.
• Steps to use Goal Seek in MS Excel :
(i) First, prepare the spreadsheet by entering data and a formula in the result cell.
(ii) Select the cell that contains the formula whose result you want to change.
(iii) Go to the Data tab → What-If Analysis → Goal Seek.
(iv) In the Goal Seek dialog box, enter the target value in To value and select the input cell in By changing cell.
(v) Click OK. Excel will calculate and display the required input value to achieve the goal.

3. Explain any two data models.
Answer – A data model defines the way data is organized, stored, and related in a database. It helps users understand the structure of data.
• Two important data models are explained below :
(i) Hierarchical Data Model – In the hierarchical data model, data is arranged in a tree-like structure with a single root node at the top. Each parent record can have multiple child records, but each child record has only one parent, representing a one-to-many (1:N) relationship. This model is easy to understand but not very flexible.
Example: An organizational chart where one manager controls many employees.
Analogy: Like folders in a computer, where one main folder contains several subfolders.
(ii) Relational Data Model – In the relational data model, data is stored in tables (relations) made up of rows (records) and columns (fields). Different tables are linked to each other using common keys, which makes data handling flexible and efficient. This model is widely used in modern databases and supports powerful query languages like SQL.
Example: A Student table linked with a Courses table using StudentID.
OR
Explain various objects of RDBMS.
Answer – An RDBMS (Relational Database Management System) uses different objects to store, organize, and manage data efficiently.
• The main objects of RDBMS are explained below :
(i) Tables – Tables are the fundamental objects of an RDBMS. They store data in the form of rows (records) and columns (fields). Each table represents a real-world entity. Example: A Students table having StudentID, Name, and Class columns.
(ii) Queries – Queries are used to retrieve specific data from one or more tables by applying conditions. They help in searching, filtering, and sorting data. Example: Displaying all students of Class 10.
(iii) Forms – Forms provide a user-friendly interface to enter, view, and edit data stored in tables. They reduce data entry errors and make data handling easier. Example: A student registration form.
(iv) Reports – Reports are used to present data in a formatted and printable form. They are mainly used for summaries and analysis. Example: A mark sheet or class attendance report.
(v) Keys (Primary Key and Foreign Key) – Keys are used to identify records and create relationships between tables. A Primary Key uniquely identifies each record and cannot be empty, while a Foreign Key links one table to the primary key of another table. Example: StudentID as Primary Key and CourseID as Foreign Key.
4. Explain primary key and foreign key with an example.
Answer – Primary Key : A Primary Key is a field in a table that uniquely identifies each record. It must contain unique values and cannot be empty (NULL). Example: In a Students table, StudentID is the Primary Key.
• Foreign Key : A Foreign Key is a field in one table that refers to the Primary Key of another table and is used to create a relationship between tables. Example: In an Enrollments table, StudentID is a Foreign Key linked to StudentID in the Students table.
5. Explain “many-to-many” relationship in database.
Answer – A many-to-many (M:N) relationship in a database occurs when one record in Table A can be linked to many records in Table B, and one record in Table B can also be linked to many records in Table A. Such a relationship is implemented using a junction (intermediate) table, which contains foreign keys from both related tables and converts the relationship into two one-to-many relationships.
Example: In a Student-Course database, one student can enroll in many courses, and one course can have many students. An Enrollment table is used to connect Students and Courses.
OR
Explain options in Libre Office Base to maintain referential integrity.
Answer – In LibreOffice Base, referential integrity is maintained using options available in the Relationship dialog box to ensure data consistency and avoid orphan records.
• Enforce Referential Integrity – Ensures that the foreign key value in the child table always matches an existing primary key value in the parent table, thus preventing orphan records.
• Cascade Update / Cascade Delete – Automatically updates related foreign key values when the primary key is changed and deletes related records in the child table when a parent record is deleted.
• Set Null / Set Default – Sets the foreign key field to NULL or to a default value in the child table when the related parent record is updated or deleted.
6. Write steps to use fill format option.
Answer – Steps to use fill format option :
(i) First, select the text, paragraph, or object that already has the required formatting, such as font style, font size, color, alignment, or spacing, which you want to copy to other parts of the document.
(ii) Next, open the Styles and Formatting window by pressing F11, and then click on the Fill Format Mode icon (paint bucket/paintbrush) to activate the format copying tool.
(iii) Finally, click or drag over the target text, paragraph, or object where you want to apply the same formatting. After applying the format, press Esc to exit the Fill Format Mode.
OR
Write note on text wrapping tools.
Answer – Text wrapping is a feature of word processing and desktop publishing software that controls how text flows and adjusts around objects such as images, shapes, or tables in a document. It allows text to appear on the left, right, both sides, or around the object, helping to arrange content neatly. Text wrapping improves the layout, readability, and overall appearance of a document.
7. What is consolidate function? What things need to be checked before consolidating data?
Answer – The Consolidate function in a spreadsheet is used to combine and summarize data from different worksheets into one summary sheet using functions like SUM, AVERAGE, COUNT, MAX, or MIN.
• Things to be checked before consolidating data :
(i) The data structure and data types should be similar in all sheets (same rows, columns, and numeric data).
(ii) The labels/headings (such as names, months, or products) must be identical and placed in the same position.
(iii) The primary column or key field (like Student Name or Month) should be consistent across all sheets for correct grouping.
8. What are responsibilities of employer for workplace safety?

(iii) Ensure safety training and facilities by training workers in safe work practices, providing personal protective equipment (PPE), and arranging emergency and first-aid facilities.
9. How goals can be set?
Answer – Goals can be set by using the SMART method, which means goals should be specific, measurable, achievable, relevant, and time-bound. First, decide clearly what you want to achieve, then break the goal into small and practical steps so it becomes easier to complete. Setting priorities, fixing a time limit, and regularly checking progress help in staying focused and successfully achieving the goal.
