Rajasthan Police Constable Mock Test - 1 - Rajasthan Police Constable MCQ

The logic followed is:

In all the options, except option (4), the first is organized in the second.

Sports are organized on the Ground.

Cinema is shown on the screen.

Drama is played on Stage.

But

Rubber is used to erase the writing. Thus this is different from the rest.

Hence, the correct answer is "Option 4".

The pattern followed here is:

• B is the mirror image of A and this mirror image inside the two square.

Similarly,

• D is the mirror image of C and this mirror image inside the two square.

Hence, 'Option (4)' is the correct answer.

The logic is :

1) XYADH

2) PQSVZ

3) EFHKO

4) TUWYC

Hence, 'TUWYC' is the odd letter cluster.

The pattern followed here is:

Given: 34, 71, 108, 145, ?, 219

Hence, the correct answer is "182".

The distance and direction diagram as per the given information:

The shortest distance is OD =?

In triangle OED:

DE = 6 km ; OE = (6 + 2) = 8 km

Apply the Pythagoras theorem:

DO² = DE² + OE²

DO² = (6)² + (8)² = 36 + 64 = 100 km

DO = 10 km

Here, the shortest distance between her town and the tennis court in Delhi is 10 km and the direction of the town from the tennis court is North-West.

Hence, the correct answer is "10 km; North-west ".

The table shows the place value of the alphabet from A to Z.

The logic followed here is:

Logic: (Sum of the place of the alphabets) × (multiply by numbers of alphabets)

‘GOD' is coded as 78

GOD → [G(7) + O(15) + D(4)] × 3 → (7 + 15 + 4) × 3 → 26 × 3 → 78

‘GREAT' is coded as 255,

GREAT → [G(7) + R(18) + E(5) + A(1) + T(20)] × 5 → (7 + 18 + 5 + 1 + 20) × 5 → 51 × 5 → 255

Similarly, GIFT coded as

GIFT → [G(7) + I(9) + F(6) + T(20)] × 4 → (7 + 9 + 6 + 20) × 4 → 42 × 4 → 168

Therefore, GIFT is coded as '168'.

Hence, the correct answer is "Option (4)".

According to the given information,

Wall → Roof, Roof → Door, Door → Window, Window → Floor

We use ‘door’ to enter and exit a building and here ‘Door’ is called a ‘Window’.

Hence, the answer is ‘Window’.

The mirror image created will be as follows:

Hence, the mirror image will be the image created above.

Hence, the figure in option 1) will complete the pattern.

The patter followed is,

The figure moves clockwise direction after one space.

The figure which will come next in the pattern is,

Hence, option 3 is the correct answer.

BODMAS Table

Given equation : 84 * 6 * 25 * 13 * 3

Option 1) ÷, +, =, × by subsituting these value according to BODMAS table we get

84 ÷ 6 + 25 = 13 × 3

14 + 25 = 13 × 3

14 + 25 = 39

39 = 39(LHS = RHS)

Option 2) =, -, +, ×

84 = 6 - 25 + 13 × 3

84 = 6 - 25 + 39

84 = 45 - 25

84 ≠ 20(LHS ≠ RHS)

Option 3) +, ÷, =, ×

84 + 6 ÷ 25 = 13 × 3

84 + 0.24 = 13 × 3

84 + 0.24 = 39

84.24 ≠ 39(LHS ≠ RHS)

Option 4) -, -, =, +

84 - 6 - 25 = 13 + 3

84 - 6 - 25 = 16

84 - 31 = 16

53 ≠ 16(LHS ≠ RHS)

Hence, "÷, +, =, ×" is the correct answer.

Except for NOQ, in all other options, each letter is the second successor of the previous letter as per the English alphabetical series as shown below.

Hence, NOQ is different from the other three.

The correct mirror image of the given figure when the mirror is held at the side is:-

Hence, "option 3" is the correct answer.

The logic follows here is :-

'BOMBAY' is coded as "CPNYAB".

and

'STUPID' is coded as "TUVDIP".

Physical layer

Concept:-

In the OSI model, a hub is specified at the physical layer. Hubs regenerate electrical signals defined at the Physical layer.

Key Points

• The primary distinction between hubs, switches, and bridges is that hubs function at Layer 1 of the OSI model, whereas bridges and switches operate at Layer 2.
• They link numerous computers by transferring data from one port to all of its other ports without restriction. Hubs work in half-duplex mode.
• A hub is a physical layer networking device that connects many network devices. They are typically used to link computers in a LAN.
• A hub contains numerous ports. A computer that will connect to the network is hooked into one of these ports.

Additional Information

Session layer:- The Session Layer is the layer of the ISO Open Systems Interconnection (OSI) paradigm that governs computer dialogues (connections). It creates, manages, and closes connections between local and remote applications.

Data link layer:- The data connection layer is the protocol layer in a program that handles data movement into and out of a network's physical links.

Application layer:- The application layer is an abstraction layer that defines the shared protocols and interface methods that hosts in a communication network utilize.

The correct answer is LAN with 10 Mbps speed is called 'Ethernet'.

Key Points

• Ethernet (the name commonly used for IEEE 802.3 CSMA/CD) is the dominant cabling and low-level data delivery technology used in local area networks (LANs).
• Ethernet transmits data at up to ten million bits (i.e., 10 megabits) per second (10 Mbps).
• Connectivity provided via Ethernet cable is typically much faster than broadband connectivity.

Additional Information

• A local area network (LAN) consists of a series of computers linked together to form a network in a circumscribed location.
• The computers in a LAN connect to each other via TCP/IP ethernet or Wi-Fi.
• A LAN is normally exclusive to an organization, such as a school, office, association or church.

• Spam emails can be harmful to the recipient's privacy, security, and productivity.

Additional Information

• Anti-virus:
  • It is a software designed to protect a computer or network from malware and other threats.

• Rootkit:
  • A rootkit is a type of malware that is designed to hide its presence and activities from the user and the anti-virus software.
  • Rootkits can be used to gain unauthorized access to a computer or network, steal data, or perform other malicious activities.
  • However, rootkits are not directly related to spam emails, and can be detected and removed by specialized anti-malware tools.

Concept:

Work:

• Work is said to be done by a force on an object if the force applied causes a displacement in the object.
• The work done by the force is equal to the product of force and the displacement in the direction of the force.
• Work is a scalar quantity.
• Its SI unit is Joule(J).

Explanation:

• So, From the expression of work, it is very clear that the work done depends upon, the applied force, displacement and angle between them.
• It does not depend upon the initial velocity of the object.

So, the correct option is the Initial velocity of the object.

Mistake Points

• The work-energy theorem says work done is equal to a change in Kinetic energy.
• So, it seems the work depends upon initial velocity, but in actual it depends upon the change in kinetic enrgy and hence change in speed not initial velocity.

The correct answer is Uttarakhand.
