Correct answer is option 'D'. Can you explain this answer?

Given H = 8 which means H is 8th letter in alphabet series.
Similarly,
HAT = 29 → H + A + T = 8 + 1 + 20 = 29
So the code number for BOX will be,
B + O + X = 2 + 15 + 24 = 41

  • d)
    Both conclusion I and II follow
Correct answer is option 'D'. Can you explain this answer?

Understanding the Statements
Given the statements:
- Statement I: All film stars are playback singers.
- Statement II: All film directors are film stars.
These statements set the foundation for analyzing the conclusions.
Analyzing Conclusion I
- Conclusion I: All film directors are playback singers.
From Statement II, we know that all film directors are included in the category of film stars. Since Statement I states that all film stars are playback singers, we can deduce that all film directors, being film stars, must also be playback singers. Thus, Conclusion I logically follows.
Analyzing Conclusion II
- Conclusion II: Some film stars are film directors.
Given Statement II, which states that all film directors are film stars, it implies that there exists at least one group of film stars that consists of film directors. Therefore, it logically follows that some film stars are indeed film directors. Hence, Conclusion II also logically follows.
Final Evaluation
Both conclusions are substantiated by the initial statements:
- Conclusion I is true because film directors, as film stars, must also be playback singers.
- Conclusion II is true because the existence of film directors within the broader category of film stars implies that there are indeed some film stars who are film directors.
Conclusion
Since both conclusions are validated by the statements, the correct answer is:
d) Both conclusion I and II follow.

In 453 : 99
⇒ 453 = 4 + 5 + 3 = 12;
12 + 12/2 = 12 + 6 = 18
⇒ 99 = 9 + 9 = 18
Similarly,
⇒ 642 = 6 + 4 + 2 = 12
⇒ 12 + 12/2 = 12 + 6 = 18
1) 765 ⇒ 7 + 6 + 4 = 17
2) 346 ⇒ 6 + 4 + 3 = 13
3) 867 ⇒ 8 + 6 + 7 = 21
4) 396 ⇒ 3 + 9 + 6 = 18
Hence, 396 will be correct option.

  • d)
    Mesh topology
Correct answer is option 'D'. Can you explain this answer?

Ayush Kumar answered
Mesh Topology: Highest Reliability

Mesh topology is considered to have the highest reliability among the given options. This is primarily due to its redundant and interconnected nature. Let's understand why mesh topology is more reliable compared to other topologies.

1. Redundancy:
In a mesh topology, every node is connected to every other node in the network. This ensures multiple paths for data transmission. If one path fails or becomes congested, there are alternative paths available to transmit the data. This redundancy greatly enhances the reliability of the network by reducing the chances of a single point of failure.

2. Fault Tolerance:
Mesh topology provides high fault tolerance as it can easily identify and isolate faulty nodes or links. If a node or link fails, the network can reroute the traffic through other available paths. This dynamic rerouting capability helps in maintaining uninterrupted communication within the network.

3. Scalability:
Mesh topology is highly scalable as new nodes can be easily added to the network without disrupting the existing connections. This flexibility allows the network to adapt to changing requirements and expand as needed. The ability to add more nodes ensures that the network can handle increasing traffic and maintain reliability even as the network grows.

4. Security:
Mesh topology provides enhanced security compared to other topologies. With multiple paths available, it becomes difficult for unauthorized users to intercept or manipulate data packets. Additionally, the decentralized nature of the mesh network makes it more resistant to attacks and ensures better data protection.

5. Performance:
Mesh topology offers excellent performance due to its high bandwidth availability. Since each node is connected to every other node, there is no contention for network resources. This minimizes data congestion and latency issues, resulting in faster and more efficient data transmission.

Overall, the redundant and interconnected nature of mesh topology makes it the most reliable among the given options. It provides fault tolerance, scalability, security, and high-performance capabilities, making it suitable for critical applications where uninterrupted communication is essential.

    zci
  • b)
    ajp
  • c)
    das
  • d)
    None of  these
Correct answer is option 'D'. Can you explain this answer?

Mahesh Singh answered
Understanding the Code Language
To decode the statements, we will analyze the given phrases and identify the common words and their corresponding codes.
Phrase Analysis
1. mxy das zci translates to good little frock
- Here, 'good' = mxy, 'little' = das, 'frock' = zci.
2. Jmx cos zci translates to girl behaves good
- In this case, 'girl' = Jmx, 'behaves' = cos, 'good' = zci.
3. das ajp cos translates to little girl fell
- Here, 'little' = das, 'girl' = ajp, 'fell' = cos.
Identifying Key Words
- From the first phrase, we can conclude that 'frock' corresponds to the code zci.
- In the second phrase, 'good' is identified as zci, which confirms 'good' and 'frock' share the same code.
- In the third phrase, 'little' remains consistent with das, while 'girl' corresponds to ajp.
Conclusion
Now analyzing the codes:
- zci appears in both the first and second phrases, confirming its meaning as good and also linking it to frock.
- There is no distinct code for frock that separates it from good.
Since the code for frock is not uniquely identifiable and shares its code with good, we conclude:
Answer
The word for frock cannot be definitively determined from the provided data, hence the correct answer is None of these (D).

Correct answer is option 'A'. Can you explain this answer?

Ashwin Kapoor answered
Understanding the Statement
The given statement indicates that if mileage and looks are your criteria for buying a car, then Renault’s Duster is the best choice. This means that under the conditions specified, the Duster excels in both areas.
Analyzing the Conclusions
1. Conclusion I: Renault Duster gives good mileage.
- The statement implies that Renault Duster is suitable if mileage is a criterion. Therefore, it can be logically concluded that the Duster must offer good mileage, as it is labeled as the "best bet" for those prioritizing mileage.
2. Conclusion II: It is the best looking car of all times.
- The statement does not claim that the Renault Duster is the best-looking car of all time; it only states that it is the best choice if looks are a criterion. The phrase "best bet" does not equate to being the best in an absolute sense but rather the best among the options considered under those specific criteria.
Final Evaluation
- Conclusion I follows logically from the statement, as it directly supports the assertion made about the Duster’s mileage.
- Conclusion II does not follow, as the statement lacks any information to support the claim of being the best looking car of all times.
Conclusion
Based on the analysis, the correct answer is option 'A': Only conclusion I follows.

Correct answer is option 'D'. Can you explain this answer?

Raj Desai answered
Understanding the Series
The series provided is: YZ, VW, ST, ?, MN.
Identifying the Pattern
- The series consists of pairs of letters.
- Analyzing each pair:
- YZ: Y is the 25th letter of the alphabet, Z is the 26th.
- VW: V is the 22nd letter, W is the 23rd.
- ST: S is the 19th letter, T is the 20th.
Letter Positioning
- Each pair is formed by two consecutive letters.
- The first letter of each pair decreases by 3 in position:
- Y (25) to V (22) is a decrease of 3.
- V (22) to S (19) is again a decrease of 3.
Continuing the Pattern
- Following this pattern:
- The next first letter after S (19) would be P (16), which is 3 positions back.
Finding the Second Letter
- The second letter of each pair is also consecutive, following the first letter:
- Z (26) follows Y, W (23) follows V, and T (20) follows S.
- Therefore, the second letter after P should be Q (17).
Conclusion
- The missing term in the series is PQ, which completes the sequence as:
- YZ, VW, ST, PQ, MN.
Thus, the correct answer is option D: PQ.

Correct answer is option 'B'. Can you explain this answer?

Raj Desai answered
Arranging Words in Dictionary Order
To determine the order of the words, we need to compare them letter by letter, just like in a dictionary. Here’s how the words stack up:
Words to Arrange
- Specific
- Spectacle
- Specified
- Spectacular
Step-by-Step Comparison
1. First Letter Comparison:
All words start with 'S', so we move to the second letter.
2. Second Letter Comparison:
- Specific (p)
- Spectacle (p)
- Specified (p)
- Spectacular (p)
All words share 'p' as the second letter. Move to the third letter.
3. Third Letter Comparison:
- Specific (e)
- Spectacle (e)
- Specified (c)
- Spectacular (e)
‘Specific’, ‘Spectacle’, and ‘Spectacular’ share 'e', so we compare ‘Specified’ which has 'c' and comes first among the words starting with ‘p’.
Current Order
1. Specified
2. Specific
3. Spectacle
4. Spectacular
Final Arrangement
So the final dictionary order of the words is:
1. Specified
2. Specific
3. Spectacle
4. Spectacular
Identifying the Second Word
From the final arrangement:
- The second word is Specific.
Conclusion
The correct answer is option B (3), which represents 'Specified' as the first word and 'Specific' as the second word.

Rasik walked 20 m towards north. Then he turned right and walks 30 m. Then he turns right and walks 35 m. Then he turns left and walks 15 m. Finally he turns left and walks 15 m. In which direction and how many metres is he from the starting position?
  • a)
    15 m West
  • b)
    30 m East
  • c)
    30 m West
  • d)
    45 m East
Correct answer is option 'D'. Can you explain this answer?


Steps to solve the problem:

1. Initial Movement:
Rasik starts by walking 20 m towards the north.

2. First Turn:
After walking 20 m north, he turns right and walks 30 m.

3. Second Turn:
Then he turns right again and walks 35 m.

4. Third Turn:
Next, he turns left and walks 15 m.

5. Final Turn:
Lastly, he turns left again and walks 15 m.

Calculating the final position:
- From the initial position, he walked 30 m east and 35 m south.
- This creates a right-angled triangle with sides of 30 m and 35 m.
- Using the Pythagorean theorem, we can calculate the hypotenuse:
c² = a² + b²
c² = 30² + 35²
c² = 900 + 1225
c² = 2125
c = √2125
c ≈ 46.1 m

Answer:
Rasik is approximately 46.1 m east and 15 m north from the starting position.
Therefore, he is 46.1 m east and 15 m north from the starting position.
