Test: Mental Ability (Classification) - Software Development MCQ

Hence, "Printer" is the correct answer.

Important PointsInput Device: A piece of equipment/hardware that helps us enter data into a computer is called an input device. For example keyboard, mouse, etc. 

1. Keyboard:

• A simple device comprising keys and each key denotes either an alphabet, number, or number commands which can be given to a computer for various actions to be performed
• It has a modified version of typewriter keys
• The keyboard is an essential input device and computers and laptops both use keyboards to give commands to the computer

2. Joy Stick:

• It is a device that comprises a stick that is attached at an angle to the base so that it can be moved and controlled
• Mostly used to control the movement in video games
• Apart from a computer system, a joystick is also used in the cockpit of an aeroplane, wheelchairs, cranes, trucks, etc. to operate them well

3. Scanner:

• This device can scan images or text and convert it into a digital signal
• When we place any piece of a document on a scanner, it converts it into a digital signal and displays it on the computer screen

Output Device: A piece of equipment/hardware that gives out the result of the entered input, once it is processed (i.e. converts data from machine language to a human-understandable language), is called an output device. For example printers, monitors, etc. 

Printer:

• A device that makes a copy of the pictorial or textual content, usually over a paper is called a printer
• For example, an author types the entire book on his/her computer and later gets a printout of it, which is in the form of paper and is later published
• Multiple types of printers are also available in the market, which can serve different purposes

The logic followed here is:

The place value of A is 1, D is 4, O is 15 and U is 21. 

In each of the given figure the alphabet and its place value are given except  U and 23 in figure D.

Hence, figure D is the odd one from the given figures.

The logic is :

1) BEH

2) KNR

3) GJM

4) TWZ

Hence, 'KNR' is the odd letter.

The logic followed is:

All the other options except option (3), the the number given are prime number whereas option 3 is a perfect cube. 

Option 1: 47

It is a prime number.

Option 2: 17

It is a prime number.

Option 3: 27

It is a perfect cube of 3.

Option 4: 37

It is a prime number..

Hence, the correct answer is "Option 3".

Trapezoid, Rhombus, and Parallelogram are the 2 dimensional figure.

While;

Prism is a 3-dimensional figure.

Hence, "Prism" is the correct answer.

Important Points

The pattern followed is, 

Logic: For all the other option sum of place value is 14 except “DJA”

Hence, “DJA” is the correct answer.

The logic followed here is:

1) Intact and Unflawed are synonyms meaning not damaged and perfect.

2) Entire and Partial are antonyms.

3) Bright and Luminous are synonyms.

4) Pure and Perfect are synonyms.

Both the words are synonyms in all the options except option 2, where the given words are antonyms.

Hence, the correct answer is "Entire : Partial".

The logic is:

the pattern being followed here is:

(Number)² : (Number)³

1. 225 : 3375 → 15² : 15³

2. 49 : 280 → 7² : 7³ = 343 ≠ 280

3. 64 : 512 → 8² : 8³

4. 25 : 125 → 5² : 5³

Hence, ‘49 : 280’ is the odd one out. 

The description is as follows:

Hence, ‘COW’ is the odd one out.

The logic followed here is:

• In each figure A, B, and C, the image is divided into two equal parts and one of the parts is shaded whereas, in figure D more than half of the figure is shaded. 

Hence, figure D is the odd one out of the given figures.
