Books are bought at the rate of 8 for Rs. 560. To make a profit of 60%, these books must be sold at:
A)
5 for Rs. 560
B)
6 for Rs.560
C)
5 for Rs. 570
D)
6 for Rs. 570
Cost price of 8 books = Rs. 560, so cost price of 1 book = 560/8 = Rs. 70. For a profit of 60%, selling price of 1 book = 70 × 1.6 = Rs. 112. Now check the options: if 5 books are sold for Rs. 560, then selling price of 1 book = 560/5 = Rs. 112, which matches the required price. Hence the correct answer is option (a). Other options give per-book selling prices different from Rs. 112, so they do not yield 60% profit.
Which of the following are the functions of an Operating System? I. Manages computer resources very efficiently II. Takes care of scheduling jobs for execution III. Manages the flow of data and instructions
A)
I and III only
B)
I, II and III
C)
II and III only
D)
I and II only
An operating system performs all three listed functions. I: It manages computer resources such as CPU, memory, storage, and I/O devices efficiently. II: It schedules jobs/processes for execution through CPU scheduling and process management. III: It manages the flow of data and instructions between hardware, software, memory, and input/output operations. Therefore, all statements are correct. Options (a), (c), and (d) are incorrect because they omit one or more valid functions of an operating system.
In power point, which menu is used to apply various visual effects to the slide?
A)
View
B)
Design
C)
Slide show
D)
Transitions
In MS PowerPoint, the Transitions menu/tab is used to apply visual effects when moving from one slide to another. These effects include fade, wipe, split, and similar slide-change animations.
Why others are incorrect:
- View: used to change the display mode of slides.
- Design: used to change themes, background, and overall slide appearance.
- Slide show: used to run or set up the presentation, not mainly for applying transition effects.
- Transitions: specifically used for slide visual effects.
Three numbers are in the ratio 2 : 3 : 4. Their HCF is 12. The sum of the numbers is:
A)
72
B)
108
C)
110
D)
120
Let the three numbers be 2x, 3x, and 4x. Since 2, 3, and 4 are coprime as a ratio set, their HCF is x. Given HCF = 12, we get x = 12. So the numbers are 24, 36, and 48. Their sum = 24 + 36 + 48 = 108. Hence, the correct option is (b).
Which of the following is a programming language?
A)
Opera
B)
Python
C)
Windows
D)
Android
Python is a programming language used to write software, scripts, and applications. Opera is a web browser, Windows is an operating system, and Android is a mobile operating system. Therefore, the correct answer is Python.
What is the primary role of DNS in the web?
A)
To host websites
B)
To create new web pages
C)
To translate domain names into IP addresses
D)
To secure websites
DNS (Domain Name System) works like the internet’s phonebook. When a user enters a domain name such as www.example.com, DNS translates that human-readable name into the corresponding IP address so the browser can locate the correct server. इसलिए option (c) is correct. Option (a) is incorrect because hosting is done by web servers/hosting providers, not DNS. Option (b) is incorrect because DNS does not create web pages. Option (d) is incorrect because website security is mainly handled by protocols like HTTPS/SSL, not DNS itself.
How many bits are there in an IPv6 address?
A)
32 bits
B)
64 bits
C)
128 bits
D)
256 bits
An IPv6 address is 128 bits long. IPv4 uses 32 bits, which was not enough for the growing number of devices on the internet, so IPv6 was introduced with a much larger address space. Therefore, option (c) is correct. Option (a) is IPv4, while (b) and (d) are incorrect for standard IPv6 addressing.
IMAP is an email-related communication protocol. What is the full form of IMAP?
A)
Internet Media Access Protocol
B)
Intranet Message Access Protocol
C)
Internet Message Access Protocol
D)
Intranet Media Access Protocol
IMAP stands for Internet Message Access Protocol. It is an email retrieval protocol that allows users to access and manage emails directly on the mail server.
Why others are incorrect:
(a) Internet Media Access Protocol — incorrect expansion of IMAP.
(b) Intranet Message Access Protocol — IMAP is used over the Internet, not specifically an intranet.
(d) Intranet Media Access Protocol — both 'Intranet' and 'Media' are incorrect.
A computer program that converts an entire program into machine language is called:
A)
Interpreter
B)
Simulator
C)
Compiler
D)
Programmer
A compiler translates the entire source program into machine language at once, producing object/executable code. An interpreter translates and executes the program line by line, so option (a) is incorrect. A simulator imitates the working of another system, so option (b) is incorrect. A programmer is a person who writes programs, so option (d) is incorrect.
Operating system, editors, and debuggers comes under:
A)
System Software
B)
Application Software
C)
Utilities
D)
None of the above
Operating systems, editors, and debuggers are all examples of system software because they help run, control, and support the computer system and application programs. Application software is meant for end-user tasks like word processing or accounting. Utilities are a subset of system support tools, but the broader and correct category covering operating systems, editors, and debuggers together is system software.
In MS-word, ‘Ctrl+Home’ is used to:
A)
Move the cursor to the beginning of Document
B)
Move the cursor to the beginning of Line
C)
Move the cursor to the beginning of Paragraph
D)
None of the above
In MS Word, the shortcut Ctrl + Home moves the insertion point/cursor directly to the start of the entire document. Therefore, option (a) is correct. Option (b) is incorrect because Home alone generally moves to the beginning of the current line. Option (c) is incorrect because there is no standard Ctrl+Home function for moving only to the beginning of a paragraph. Hence, (d) is also incorrect.
The ‘Page Layout’ tab in word processing software (like Microsoft Word) is used to adjust:
A)
Inserting hyperlinks
B)
Text colour
C)
Fonts and paragraphs
D)
Margins, orientation, and size
The Page Layout tab (called Layout in newer versions of MS Word) is mainly used to control page setup features such as margins, page orientation (portrait/landscape), and paper size.
Why others are incorrect:
(a) Inserting hyperlinks is done from the Insert tab.
(b) Text colour is usually changed from the Home tab under Font settings.
(c) Fonts and paragraphs are mainly managed from the Home tab.
Therefore, the correct answer is option (d).
The main electronic component used in first generation computers was:
A)
Transistors
B)
Vacuum Tubes (or valves)
C)
Integrated Circuits
D)
Microprocessors
First generation computers (about 1940s–1950s) used vacuum tubes as their main electronic switching component. These tubes were large, consumed much power, and produced a lot of heat. Transistors were used in second generation computers, integrated circuits in third generation computers, and microprocessors in fourth generation computers. Therefore, option (b) is correct.
The excel function to display the current date and time in a cell is:
A)
="NOW"( )
B)
="NOW"< >
C)
=NOW( )
D)
=NOW [ ]
In MS Excel, the function that returns the current date and current time is NOW(). Therefore the correct syntax is =NOW().
Why option (c) is correct:
- Excel functions begin with =
- The function name is NOW
- Function arguments, if any, are written inside parentheses
- NOW takes no arguments, so it is written as =NOW()
Why the other options are incorrect:
- (a) ="NOW"( ): Uses quotation marks, which would make it text, not a function name.
- (b) ="NOW"< >: Uses quotation marks and incorrect brackets.
- (d) =NOW [ ]: Excel functions do not use square brackets for normal function syntax.
This error message appears when a formula that refers to a cell, sheet, or range is invalid for calculation:
A)
#NAME
B)
$VALUE
C)
#REF
D)
#ERR
The correct answer is #REF. In MS Excel, the #REF! error appears when a formula contains an invalid cell reference, such as when a referenced cell, range, or sheet has been deleted or is no longer valid.
Why others are incorrect: (a) #NAME? occurs when Excel does not recognize text in a formula, such as a misspelled function name. (b) #VALUE! occurs when the wrong type of argument or operand is used. (d) #ERR is not a standard Excel error message.
Which of the following is not a peripheral device?
A)
Mouse
B)
Keyboard
C)
Motherboard
D)
Printer
Peripheral devices are external or auxiliary hardware used for input, output, or storage, such as a mouse, keyboard, and printer. The motherboard is not a peripheral device; it is the main internal circuit board of the computer that connects and allows communication between all core components. Therefore, option (c) is correct, while (a), (b), and (d) are all peripheral devices.
How can you apply a design theme to your PowerPoint presentation? I. Right-click on the slide and choose “Apply Theme” II. Go to the “Design” tab and select a theme III. Use the “Home” tab and click “Themes”
A)
I and III only
B)
II Only
C)
III only
D)
I and II only
In Microsoft PowerPoint, design themes are applied from the Design tab by selecting a theme. So statement II is correct. Statement I is not the standard method because right-clicking a slide does not generally provide an 'Apply Theme' option as the main way to apply themes. Statement III is incorrect because the Home tab does not contain the Themes command. Therefore, only II is correct.
In power point, what can be considered as the easiest way to place the same graphic in the same place in all slides?
A)
Place graphic in Notes Master
B)
Place graphic in Slide Master
C)
Place graphic in Handout Master
D)
Place graphic manually in all slides
In Microsoft PowerPoint, the Slide Master controls the common design and layout elements for all slides in a presentation. If you place a graphic in the Slide Master, it will appear in the same position on all slides that use that master. Notes Master affects printed notes pages, Handout Master affects printed handouts, and placing the graphic manually on every slide is not the easiest method.
Find the middle letter between 9th and 19th letters in the English alphabet.
A)
N
B)
L
C)
P
D)
M
The 9th letter of the English alphabet is I and the 19th letter is S. Counting the positions, the middle letter between 9 and 19 is the average: (9 + 19) / 2 = 14. The 14th letter is M. Therefore, the correct answer is option (d) M.
In a camp, there is a meal for 210 men or 300 children. If 200 children have taken the meal, how many men will be catered to with the remaining meal?
A)
40
B)
50
C)
60
D)
70
The total meal is equal to either 210 men or 300 children. So, 1 man's meal = 300/210 = 10/7 children's meal. If 200 children have eaten, the remaining meal is for 300 - 200 = 100 children. Since 10 children’s meal = 7 men’s meal, 100 children’s meal = (100 × 7)/10 = 70 men. Hence, the correct answer is 70. Options (a), (b), and (c) are incorrect.
A packet of information that travels between a browser and the web server is a:
A)
Bookmark
B)
Plug-in
C)
Cookie
D)
Extension
A cookie is a small packet of data exchanged between a web browser and a web server and stored by the browser to maintain session information, preferences, or tracking data.
Why others are incorrect:
- Bookmark: a saved web page address for future access.
- Plug-in: software component that adds specific functionality to a browser.
- Extension: add-on that enhances browser features.
Therefore, the correct answer is Cookie.
Which of the following is used to create a table of contents in MS Word?
A)
Insert -> Table of Contents
B)
Home -> Table
C)
References -> Table of Contents
D)
View -> Table of Contents
In MS Word, the Table of Contents feature is found under the References tab. From there, you can insert an automatic or custom table of contents. इसलिए option (c) is correct. Option (a) is incorrect because it is not under Insert, option (b) is incorrect because Table is not under Home, and option (d) is incorrect because View does not contain the Table of Contents command.
If each side of an equilateral triangle is divided into 4 equal parts and parallel lines are drawn, how many triangles are formed?
A)
24
B)
27
C)
30
D)
32
When each side of an equilateral triangle is divided into 4 equal parts and lines are drawn parallel to the sides, the figure becomes a triangular grid of order 4. The total number of triangles formed in such a grid is given by the standard count: 16 small triangles + 7 medium triangles + 3 larger triangles + 1 largest triangle = 27. Hence, the correct answer is 27. The other options do not match the total number of triangles in a 4-division equilateral triangle grid.
The smallest number which must be added to 5816 to make it a perfect cube is:
A)
12
B)
19
C)
16
D)
18
Find the nearest perfect cubes around 5816. We have 17^3 = 4913 and 18^3 = 5832. Since 5816 is less than 5832, the smallest number to be added is 5832 - 5816 = 16. Therefore, the correct answer is option (c).
A is B’s brother. “I have as many sisters as brothers”, tells B to one of her friends. How many brothers and sisters are there in this family?
A)
Two brothers and two sisters
B)
Two brothers and one sister
C)
One brother and two sisters
D)
One brother and one sister
Let the number of brothers be b and the number of sisters be s. B is a girl, so when she says, “I have as many sisters as brothers,” her sisters count is s - 1 (excluding herself), and her brothers count is b. Thus, s - 1 = b. Also, A is B’s brother, so there is at least one brother. Checking the options: (a) 2 brothers and 2 sisters gives for B: 1 sister and 2 brothers, which are not equal if B is one of the two sisters? Wait carefully: if total sisters are 2, then for B, sisters = 1 and brothers = 2, so not equal. Let us verify all options. (b) 2 brothers and 1 sister gives sisters = 0, brothers = 2, not equal. (c) 1 brother and 2 sisters gives for B: 1 sister and 1 brother, equal. (d) 1 brother and 1 sister gives sisters = 0, brothers = 1, not equal. Therefore the correct answer is actually (c) One brother and two sisters.
