General Mental Ability

On a straight railway track, a sequence of freight carriages is standing in a single line. Carriage $X$ is the $38^{\text{th}}$ carriage from the front end, and Carriage $Y$ is the $47^{\text{th}}$ carriage from the rear end. Carriage $Z$ is positioned exactly halfway between Carriage $X$ and Carriage $Y$. If Carriage $Z$ is the $62^{\text{nd}}$ carriage from the rear end, what is the total number of freight carriages on the track?

One evening, just before sunset, a security guard begins his patrol in an open plaza. He starts walking straight such that his shadow falls exactly to his right. He walks $20\text{ m}$ straight, then turns $135^\circ$ clockwise and walks $15\sqrt{2}\text{ m}$. Finally, he turns $135^\circ$ counter-clockwise and walks another $15\text{ m}$ straight.

What is the shortest distance between his final position and his starting point, and in which direction is his final position relative to the starting point?

An encrypted communication protocol transforms a four-letter source word into a target code using a consistent multi-step positional rule.

According to this protocol, the word $\text{FLUX}$ is transformed into $\text{SMDA}$, and the word $\text{MIND}$ is transformed into $\text{LPKU}$.

Based on the identical cryptographic logic, what will be the resulting code for the word $\text{CURE}$?

During a summit, a single straight row of delegates is seated facing South. Mr. Patel is seated $21^{\text{st}}$ from the right end of the row. Ms. Quinn is seated $28^{\text{th}}$ from the left end of the row. Dr. Ray is seated $7^{\text{th}}$ to the left of Mr. Patel and $5^{\text{th}}$ to the right of Ms. Quinn. What is the total number of delegates in the row?

Six historical monuments—Alhambra, Big Ben, Colosseum, Machu Picchu, Parthenon, and Stonehenge—are scheduled for renovation over a period of six months, from January (1st) to June (6th). The renovation schedule strictly follows these conditions:

- There is exactly one monument scheduled for renovation between Machu Picchu and Alhambra.
- Big Ben is scheduled immediately before the Parthenon.
- The Colosseum is scheduled somewhere after Machu Picchu, but it is not the final monument (6th) to be renovated.
- Stonehenge is scheduled immediately before Alhambra.
- Stonehenge is scheduled somewhere before the Parthenon.

Arrange the monuments in their correct renovation sequence from January (1st) to June (6th).

A prominent industrial facility was inaugurated on March $15$, $1897$, which happened to be a Monday. The facility's operational license mandated a comprehensive structural safety inspection exactly $10$ years later on the exact same date. What day of the week was the inspection scheduled for?

In a certain logical classification system, the word $\text{PLANET}$ is related to the letter-group $\text{KODMHG}$. Following the same analogical pattern, which of the following letter-groups corresponds to the word $\text{MODULE}$?

A digital library archiving system generates tags for its collections using a specific alphabetic transformation logic. In this system, the word INDEX is coded as GQGCA, and the word BOOK is coded as EMMN.

Using the exact same logic, what is the exact code for the word SHELF?

The second letter-group is related to the first letter-group following a specific logical pattern. Based on this same pattern, which of the following letter-groups replaces the question mark?

$\text{FLUID} : \text{XRIUZ} :: \text{SMART} : \text{?}$

In a museum's digital archiving system, historical artifacts are tagged using a specific alphabetical transformation pattern. For example, the tag for SEAL is generated as TDBK, and the tag for IRON is generated as JQPM. Based on this established coding logic, match the following artifact materials with their correct encoded tags.

Eight researchers—Aris, Boris, Celine, Darius, Ezra, Fiona, Gemma, and Hector—are seated in a single straight row. Some of them are facing North while others are facing South. Note that 'left' and 'right' directions depend on the direction a specific person is facing.

The seating arrangement follows these conditions:
1. No three adjacent researchers face the same direction.
2. Boris sits fourth from the left end of the row and faces North.
3. Darius sits to the immediate right of Boris. Darius faces South.
4. Exactly three people sit between Darius and Hector.
5. Aris sits at one of the extreme ends of the row and faces North.
6. Ezra sits to the immediate left of Aris. Ezra faces South.
7. Gemma sits to the immediate right of Ezra.
8. Celine sits second to the left of Hector.
9. The immediate neighbors of Celine face opposite directions to each other.

Based on the final seating arrangement, arrange the following researchers in their correct sitting order from the extreme left side of the row to the right side:

A futuristic space station log states that Commander Vika was born on Earth on Saturday, February 29, 2284. According to intergalactic law, she only officially celebrates her birthday when the exact date of February 29 occurs on the calendar. On what day of the week will Commander Vika officially celebrate her 5th birthday?

A global supply chain software tracks cargo shipments by encrypting destination city names to ensure data privacy. In this system, the destination "LONDON" is coded as "OLMFQP" and "BERLIN" is coded as "YVINKP". Based on this coding logic, how will the destination "MUMBAI" be coded in this tracking system?

A large solid cube is constructed using $125$ smaller, identical cubic blocks. Before the large cube is painted, all $8$ corner blocks are completely removed from the structure. The resulting modified structure is then completely dipped in a vat of red paint. After the paint dries, the structure is disassembled back into the remaining $117$ individual smaller blocks. How many of these $117$ smaller blocks have exactly two of their faces painted red?

During a data encryption analysis, a student is asked to classify four specific data blocks represented by four-letter strings. Three of these strings are generated using the identical sequential shifting rule based on the standard 26-letter English alphabet. Which of the following data blocks fails to follow the established encryption rule?

Four athletes are training on a large flat ground. Match each athlete's movement sequence with their final direction relative to their respective starting points.

Analyze the logical relationship between the entities in Column X. Then, pair each with the corresponding set of entities in Column Y that demonstrates the exact same analogical relationship.

A maritime shipping contract was enacted on Wednesday, October 14, 1795. The agreement stipulated a mandatory review and renegotiation exactly 14 years later, on October 14, 1809. On what day of the week did the renegotiation fall?

In a certain coding language, words are translated by shifting each letter forward in the English alphabet based on its positional index within the word. The first letter is shifted by one position, the second letter by two positions, the third letter by three positions, and so on. Based on this translation rule, match the given words on the left with their correctly coded equivalents on the right.

Study the logical relationship between the first pair of letter-clusters. Applying the identical underlying rule, what will replace the question mark to complete the second pair?

$\text{BIRD} : \text{ERUW} :: \text{FISH} : \text{?}$
