Explanation
The bird is flying at a speed of 100 km/hr. The two trains are moving towards each other at a combined speed of 25 km/hr (25 km/hr + 25 km/hr = 50 km/hr). Since the bird is flying at a faster speed than the trains, it will reach the other train before they clash. Therefore, the distance traveled by the bird until the trains clash is equal to the distance between the two trains, which is given as 50 km.

Explanation
The ratio of the father's age to the son's age is 10:3. This can be determined by considering the information given in the question. The father's age is 5 times that of the son's age 5 years ago, which means that the father is currently 5 years older than 5 times the son's age at that time. Similarly, the father's age is 3 times that of the son's age 2 years from now. By comparing these two expressions, we can determine that the current age ratio of the father to the son is 10:3.

Explanation
The egg vendor starts with a certain number of eggs. He sells half of his eggs (which is an even number) and half an egg. This means that the number of eggs he had initially must be an odd number.

To the second customer, he sells half of what he had left and half an egg. Since he had an odd number of eggs left after the first sale, half of that would be an odd number as well.

To the third customer, he sells half of what he had then left and half an egg. Again, since he had an odd number of eggs left after the second sale, half of that would be an odd number as well.

In the end, three eggs were remaining. This means that the number of eggs he had initially must be three more than a multiple of four. The only answer choice that satisfies this condition is 38, which is three more than a multiple of four.

Explanation

Explanation
2 weighing ( Divide the number of coins into 3 parts at each weighing)

Explanation
The runner reaches the 12th flag in 24 seconds. Since the flag poles are equidistant from each other, the runner covers 12 flag poles in 24 seconds. Therefore, the runner takes 2 seconds to cover each flag pole. To calculate the time it will take him to complete the 20th flag, we multiply the time taken for each flag pole by the total number of flag poles. So, (2 seconds/flag pole) * 20 flag poles = 40 seconds. However, none of the answer choices match this calculation, so the correct answer is not available.

Explanation
The clock rings 6 times in 30 seconds, so the time between each ring is 30/6 = 5 seconds. At 12 o'clock, the clock will ring 12 times, so the total time it takes is 5 * 12 = 60 seconds. However, this does not include the time between the first and last ring, which was 30 seconds. Therefore, the total time it takes at 12 o'clock is 60 + 30 = 90 seconds. However, none of the given options match this answer, so the correct answer is not available.

Explanation
We have: (l - b) = 23 and 2(l + b) = 206 or (l + b) = 103.

Solving the two equations, we get: l = 63 and b = 40.

Area = (l x b) = (63 x 40) m2 = 2520 m2.

Explanation
Organizational communication deals with all the patterns, networks, and systems of communication within an organization. It focuses on how information flows, is shared, and is disseminated within the organizational structure. This type of communication encompasses both formal and informal channels, as well as interpersonal interactions. It is concerned with maintaining effective communication within the organization to ensure smooth operations, coordination, and collaboration among members.

Explanation
When a manager asks an employee to complete a task, it is considered formal communication. This is because the communication is happening within the hierarchical structure of the organization, where the manager has the authority to assign tasks to employees. Formal communication follows established channels and protocols, ensuring clarity, accountability, and professionalism in the exchange of information and instructions.

Explanation
Energy has a unit of electron volt. Electron volt (eV) is a unit of energy commonly used in physics and chemistry to measure the energy of subatomic particles and interactions. It is defined as the amount of energy gained or lost by an electron when it moves through an electric potential difference of one volt. Therefore, energy is the correct answer as it is the only quantity that is measured in electron volts.

Explanation
The unit of magnetic flux in the SI system is Weber. This is because magnetic flux is defined as the total magnetic field passing through a given area, and Weber is the SI unit for magnetic flux. Maxwell is not the correct unit for magnetic flux, as it is the unit for magnetic flux density. Tesla is the SI unit for magnetic flux density, not magnetic flux. Gauss is a non-SI unit for magnetic flux density.

Explanation
Michael Faraday demonstrated the theory of electromagnetic induction in 1831. This discovery was significant in understanding the relationship between electricity and magnetism. Faraday's experiments showed that a changing magnetic field can induce an electric current in a nearby conductor. His work laid the foundation for the development of electric generators and transformers, which are essential in modern power systems. Faraday's contributions to the field of electromagnetism were groundbreaking and continue to be influential in physics and engineering.

Explanation
This circuit symbol represents a bulb. It is commonly used to indicate a light bulb or lamp in electrical diagrams and schematics. The symbol consists of a circle with a cross inside, representing the filament of the bulb. When electricity passes through the filament, it produces light.

Explanation
In a parallel circuit, the voltage across each branch remains the same. This is because each branch provides a separate path for the current to flow, and the voltage source provides the same potential difference across all branches. Therefore, the voltage does not split or divide in a parallel circuit.

Explanation
EPROM stands for Erasable Programmable Read-Only Memory. It is a type of memory that can be electrically programmed and erased using ultraviolet light. EPROM retains its programmed data even when the power is turned off, making it non-volatile. This makes it suitable for applications that require data to be stored even when the power is not available. Therefore, EPROM is the correct answer as it is both ultraviolet light erasable and electrically programmable.

Explanation
In a DC circuit, power is calculated using the formula P = V^2/R, where P is the power, V is the voltage, and R is the resistance. Rearranging the formula, we have V = sqrt(P*R). Plugging in the given values of P = 36 watts and R = 4 ohms, we can calculate V as sqrt(36*4) = sqrt(144) = 12 V. Therefore, the correct answer is c. 12 V.

Explanation
Flux is another term for magnetic lines of force. Magnetic lines of force represent the path that a magnetic field takes. Flux refers to the total number of these lines that pass through a given area. It is a measure of the strength of the magnetic field. Magnetic pole, armature, and lodestone are not synonymous with magnetic lines of force and therefore are not the correct answer.

Explanation
Inductance is a property of an electrical circuit that tends to oppose any change in current. When the current in a circuit is increasing, an inductor generates a back EMF (electromotive force) that opposes the increase in current. Similarly, when the current is decreasing, the inductor generates a forward EMF that opposes the decrease in current. This opposition to changes in current is a characteristic of inductance.

Explanation
The word "consider" means to think about or evaluate something. Similarly, the word "weigh" also means to carefully consider or think about something before making a decision. Therefore, "weigh" is the best synonym for "consider" as both words imply a thoughtful evaluation of something.

Explanation
The word "declare" means to announce or state something formally. The synonym "deem" also means to judge or consider something in a certain way. Both words involve expressing a belief or opinion about something, but "deem" is more focused on forming a judgment or perception, while "declare" is more about making a public or official statement. Therefore, "deem" is the best synonym for "declare" in this context.

Explanation
The best synonym for "maintain" is "preserve". Both words imply the act of keeping something in its original or desired state, whether it be an object, a condition, or a relationship. To preserve something means to protect, maintain, or keep it intact, which aligns with the concept of maintaining.

Explanation
The word "majority" refers to the greater part or number. An antonym for this word would be "minority," which refers to the smaller part or number. In this context, "priority" refers to something that is more important or urgent, "security" refers to safety or protection, and "impurity" refers to something that is not pure. Therefore, the correct antonym for "majority" is "minority."
