Correct Answer: C and D

A. Speed of x m/sec equals 5/18 km/hr — False

1 m/sec = 3.6 km/hr = 18/5 km/hr, not 5/18 km/hr.

B. Train running at 5/6 of its speed gets 10 min late — False

Usual time = 40 min.

New time = 40 × (6/5) = 48 min.

Delay = 48 − 40 = 8 min ≠ 10 min.

C. Car speed 80 km/hr equals 22(2/9) m/s — True

80 × (5/18) = 22.22... = 22(2/9).

D. Person crosses 600 m in 5 minutes ⇒ speed = 7.2 km/hr — True

Distance = 0.6 km, Time = 1/12 hr.

Speed = 0.6 × 12 = 7.2 km/hr.

The logic followed here is,

Thus wrong term in the series is 1738.

Hence, the correct answer is "Option 3".

The correct answer is - Assurance

Key Points

• Assurance is not considered a form of self-generated feedback.
• Self-generated feedback refers to the process where individuals evaluate, monitor, or reflect on their own performance or actions.
• Assurance is typically provided by external sources to boost confidence or validate correctness, and hence it does not fit the definition of self-generated feedback.
• Examples of self-generated feedback include previewing (looking ahead to anticipate outcomes), retracing (reviewing steps or processes), and observation (monitoring one's own behavior or outputs).

Additional Information

• Self-generated feedback involves active engagement by individuals to assess their own performance.
• Previewing: This involves anticipating potential outcomes or scenarios before performing a task. It helps individuals prepare and adjust their approach accordingly.
• Retracing: This refers to revisiting past actions, steps, or decisions to understand errors or reinforce correct processes.
• Observation: This is the act of monitoring and analyzing one's own behavior or results to identify areas of improvement or strengths.
• Assurance, on the other hand, is an external form of validation or encouragement and does not originate from the individual themselves.
• The ability to generate feedback independently is a crucial skill for self-directed learning and professional development.

Concept:

Covariance and Correlation Coefficient:

• Correlation coefficient (R) gives the strength and direction of a linear relationship between two variables X and Y.
• Covariance measures how much two variables change together.
• Relationship between correlation coefficient and covariance: ⇒ The accurate and standard formula relating correlation and covariance is: rXY​=Cov(X,Y) / S(X)S(Y)

From this, covariance is calculated as:

  Cov(X,Y)  =  rXY×S(X)×S(Y)    Cov⁡(X,Y)  =  rXY×S(X)×S(Y)

• Where:
• rXY- rXY r_{XY}

​ = correlation coefficient between XX X

 and YY

<br>

 - S(X) = standard deviation of XX X

<br>

• S(Y)- S(Y) S(Y)

 = standard deviation of YY Y

• This formula helps us compute covariance when correlation and standard deviations are given.

Calculation:

Case A: R = 0.5, S(X) = 8, S(Y) = 10

Case B: R = 4/7, S(X) = 7, S(Y) = 9

Case C: R = 0.7, S(X) = 12, S(Y) = 5

Case D: R = 19/42, S(X) = 14, S(Y) = 6

Covariances:

• A = 40
• B = 36
• C = 42
• D = 38

Ascending order: B (36), D (38), A (40), C (42)

The correct answer is - At the level of the encoder

Key Points

• At the level of the encoder
• The encoder is responsible for converting the sender's ideas, thoughts, or messages into a format that can be communicated effectively.
• If the sender fails to formulate the message properly, such as using unclear language, incorrect tone, or ambiguous expressions, it leads to a communication barrier at the encoding stage.
• This type of barrier can result in the receiver interpreting the message incorrectly or failing to understand it.
• Examples of such issues include:
• Using jargon or technical language that the receiver does not understand.
• Failure to organize the information logically.
• Inadequate clarity in expressing the intended message.

Additional Information

• Stages of Communication
• The communication process typically involves the following stages:
• Sender: Formulates the message.
• Encoder: Converts the message into a communicable format.
• Transmission: The message is sent through a communication channel (e.g., verbal, written, electronic).
• Decoder: Interprets and understands the message.
• Receiver: The individual or group who receives the message.
• Barriers can occur at any stage, but issues at the encoding stage often stem from improper formulation of the sender's message.
• Types of Communication Barriers
• Semantic barriers: Occur due to issues in language or interpretation.
• Technical barriers: Result from problems with the communication channel (e.g., noise or technical failure).
• Psychological barriers: Stem from emotional or mental factors affecting communication.
• Effective Encoding Strategies
• Use clear and concise language suitable for the audience.
• Ensure logical organization of ideas.
• Avoid ambiguity and jargon unless specifically required.

The correct answer is - Mesh topology

Key Points

• Mesh topology
• In a mesh topology, each device is connected to every other device in the network, creating a robust and redundant communication structure.
• It ensures high fault tolerance because if one connection fails, data can still be transmitted through other available paths.
• This topology is commonly used in mission-critical systems where uninterrupted communication is essential, such as in military or financial systems.
• There are two types of mesh topology:
• Full mesh topology - All devices are directly connected to every other device.
• Partial mesh topology - Some devices are connected to all others, while some are connected only to specific devices.

Additional Information

• Comparison with other topologies
• Star topology
• In a star topology, all devices are connected to a central hub or switch.
• If the central hub fails, the entire network is disrupted.
• It is simpler and less expensive than a mesh topology but less fault-tolerant.
• Bus topology
• In a bus topology, all devices share a single communication line or cable.
• It is cost-effective but prone to failures if the main cable is damaged.
• Ring topology
• In a ring topology, devices are connected in a closed loop.
• Data travels in one direction, and failure in one connection can disrupt the entire network.
• Advantages of Mesh topology
• Provides redundancy and ensures data delivery even if some connections fail.
• Offers high security because data travels through dedicated paths.
• Supports simultaneous data transfer between multiple devices.
• Disadvantages of Mesh topology
• Requires a large number of cables and ports, increasing cost and complexity.

RFID is widely used in supply chain management, asset tracking, contactless payment systems, and access control.

Key Points

• Radio Frequency (B):
• RFID stands for Radio Frequency Identification.
• Radio frequency waves are used to transmit signals between the RFID reader and the tag.
• These waves allow contactless communication, enabling long-distance scanning without a line of sight.
• Tag (A):
• An RFID tag is a small electronic device attached to an object to be tracked.
• The tag stores information such as product details, identification numbers, or access permissions.
• Tags can be active (with a battery for longer range) or passive (powered by the reader’s signal).
• Microchip (D):
• The microchip embedded inside the RFID tag stores and processes data.
• It holds the unique identification code and other relevant information.
• This is the “brain” of the RFID system, enabling secure and efficient storage of digital data.
• Antenna (C):
• The antenna in the RFID tag enables communication by receiving and transmitting signals.
• It captures radio frequency waves from the RFID reader and sends back stored information.
• Without the antenna, the microchip would not be able to interact with the external RFID reader.

Additional Information

• Compared to barcodes, RFID tags can be scanned from a distance, store more data, and do not require a direct line of sight.
• The range of RFID systems can vary: low-frequency (LF) for short-range applications, high-frequency (HF) for medium range, and ultra-high-frequency (UHF) for long-range tracking.
• RFID is considered highly reliable but may face challenges like interference from metals and liquids, as these can block or weaken radio signals.

The correct answer is: Intra-personal

Communication is generally classified into different types based on the number of participants and the context in which it occurs. When a person talks to himself/herself, thinks deeply, reflects, or dreams, it is a form of communication within the individual. This is called Intra-personal Communication, where the sender and receiver of the message are the same person. It plays an important role in self-reflection, problem-solving, and decision-making.

Key Points

• Intra-personal Communication:
• It is the process of communication that occurs within an individual.
• Examples include thinking, analyzing, self-talk, daydreaming, and recalling memories.
• The purpose is often to reflect, evaluate, and organize one’s own thoughts and feelings.
• It helps in developing self-awareness, problem-solving ability, and decision-making skills.
• Even while dreaming, the brain communicates with itself, which is also a form of intra-personal communication.

Additional Information

• Inter-personal Communication:
• This refers to direct communication between two or more individuals.
• Examples: Face-to-face conversation, phone calls, video chats, or discussions.
• It is different from intra-personal communication because it involves exchange of ideas between people, not within oneself.
• Inter-cultural Communication:
• This is communication between people from different cultural backgrounds.
• It helps in understanding diverse beliefs, values, and social norms.
• Examples include communication between people of different nations, religions, or ethnic groups.
• Inter-national Communication:
• This is communication that takes place across national boundaries between governments, organizations, or individuals of different countries.
• Examples: Diplomatic talks, international conferences, or cross-border media communication.
• Unlike intra-personal communication, this form involves external participants across nations.

Important Points

• Intra-personal communication is the most basic level of communication because it happens naturally within an individual.
• It is essential for self-evaluation, planning, and imagination.
• While interpersonal, intercultural, and international communications involve external interaction, intra-personal communication remains entirely internal.

The correct answer is - Rs. 6400

Key Points

• Simple Interest Formula
• Simple Interest (SI) is calculated using the formula: SI = (P × R × T)/100, where:
• P = Principal, R = Rate of interest per annum, T = Time in years.
• Given Details
• For first investment: P = 8000, R = 7%, T = 2 years.
• SI = (8000 × 7 × 2)/100 = Rs. 1120
• This interest is half of the interest earned on amount P over 5 years at same rate.
• Finding Principal (P)
• Let second principal = P
• (P × 7 × 5)/100 = 2 × 1120 = Rs. 2240
• P = (2240 × 100)/(7 × 5) = Rs. 6400

Additional Information

• Difference between Simple and Compound Interest
• Simple Interest is calculated only on the original principal.
• Compound Interest is calculated on principal plus accumulated interest.
• Formula for CI: CI = P(1 + R/100)^T – P

• A: No soaps are writing-tools
• This statement implies that there is no overlap between the sets of "soaps" and "writing-tools."
• It establishes a relationship of mutual exclusivity between the two sets.
• B: All soaps are non-writing-tools
• This is logically equivalent to Statement A because if no soaps are writing-tools, then all soaps must belong to the category of "non-writing-tools."
• It expresses the same idea as A but in a different format.
• D: No writing-tools are soaps
• This is also logically equivalent to Statement A because if no soaps are writing-tools, then it also follows that no writing-tools can be soaps.
• It rephrases the same exclusion relationship in a reversed order.
• Statements A, B, and D are therefore logically equivalent and represent the same relationship between "soaps" and "writing-tools."

Additional Information

• C: No non-writing-tools are soaps

• Unlike viruses, worms do not require user interaction to spread.
• HTTPS
• HTTPS (HyperText Transfer Protocol Secure) is more secure than HTTP because it uses encryption protocols such as SSL/TLS to protect data.
• HTTP (HyperText Transfer Protocol) does not provide encryption, making it vulnerable to attacks like eavesdropping.
• Trojan
• A Trojan is not an antivirus; it is a type of malware that disguises itself as legitimate software to trick users into installing it.
• Trojan programs can create vulnerabilities in systems, allowing hackers to gain unauthorized access.

The correct answer is Option 3.

 

Key Points

• The passage states, "A few people own all the means of production..."
• This sentence directly answers the question by identifying who has control over the means of production.
• The "few people" are the owners of the system, which is capitalism.
• The other classes mentioned, like the proletarial class and working class, are the ones who sell their labor, as the passage indicates.

Therefore, the maximum control over the means of production is under the Owners of the system.

 

Additional Information

• All the stake holders: This is a broad term that includes all parties with an interest in the system, not just those with maximum control.
• Proletarial class: This refers to the working class who do not own the means of production, but instead sell their labor.
• Working class: This is synonymous with the proletarial class and, as the passage notes, they have to sell their labor under conditions imposed by others.

The correct answer is Option 2.

 

Key Points

• The passage states that the capitalist system does not foster "healthy relations among human beings."
• It describes how "a few people own all the means of production" while others "have to sell their labour under conditions imposed upon them." This shows an inherent imbalance and favoritism.
• The system's focus is on "the largest profit rather than maximum production," achieved through the "exploitation of human beings."
• The passage explicitly mentions that the system "imposes injustice," which is a direct consequence of being biased.

Therefore, it can be inferred that the capitalist system is Biased.

 

Additional Information

• Ambitious: The passage does not focus on ambition, but rather on the negative consequences and inherent unfairness of the system.
• Humane: The passage directly contradicts this option by mentioning the "exploitation of human beings to the limits of endurance."
• Realistic: While the system might be a real-world model, the passage's tone is critical and highlights its negative aspects, not its practicality or realism in a positive light.

The correct answer is Option 2.

 

Key Points

• The passage states, "its concentration is on the largest profit rather than maximum production."
• The phrase "largest profit" refers to a significant financial gain, which can be seen as an "unusual benefit" or extraordinary gain compared to a normal return.
• The passage also notes that the system promotes "worship of economic power," which is a core tenet of seeking maximum profit and benefits.
• The exploitation of human beings is done to achieve this goal of "largest profit."

Therefore, the capitalist system focuses on Unusual benefits, as represented by the "largest profit."

 

Additional Information

• Maximum production: The passage explicitly states that the system focuses on "largest profit rather than maximum production."
• Investment on human resources: The passage highlights the "exploitation of human beings," which is the opposite of investing in them.
• Reduction of expenditure: While this is a means to increase profit, the passage's primary focus is on the end goal, which is "largest profit," not the method of achieving it. The best fit is the term that describes the ultimate goal.

The correct answer is Option 1.

 

Key Points

• The passage states that capitalism promotes "worship of economic power with little regard to the means employed for its acquisition and the end that it serves."
• This implies that the method of achieving wealth (the means) is less important than the wealth itself (the end).
• The system's focus on "largest profit" even through "exploitation of human beings" reinforces this idea.
• The phrase "the ends justify the means" perfectly captures this disregard for the ethical or moral methods used to achieve a desired outcome.

Therefore, in a capitalist system, it is inferred that the ends justify the means.

 

Additional Information

• The means justify the ends: This is the opposite of what the passage suggests. It would mean the methods used are more important than the final outcome.
• The means leading to exploitation are strictly prohibited: The passage explicitly states the opposite, mentioning the "exploitation of human beings."
• The religion decides the issue related to the means: The passage states that religion "rather offer a subtle defence of the established order," which means it justifies the system, but it doesn't decide the means.

The correct answer is Option 3.

 

Key Points

• The passage explicitly states that the capitalist system operates "By its exploitation of human beings to the limits of endurance..."
• It also highlights the division of society, where "a few people own all the means of production" and others "have to sell their labour under conditions imposed upon them."
• This relationship creates a clear dynamic between those who exploit and those who are exploited. The owners of the means of production are the exploiters, and the laborers who must sell their work under imposed conditions are the exploited.
• This division is the most accurate representation of the societal groups described in the passage.

Therefore, capitalism divides society into the groups of Exploiters and Exploited.

 

Additional Information

• Working and non-working: This division is too general and doesn't capture the power dynamic described in the passage. The owners of production may also be considered working.
• Buyers and Sellers: This is a transactional description that applies to any market, not specifically the exploitative relationship of capitalism as described here.
• Religious and Atheist: The passage mentions religion, but only in its role of justifying the capitalist system, not as a primary division created by the system itself.
