The pattern is placing vowels at the start in the order they appear and consonants at the end in reversed order. “SARASWATI” → vowels: A, A, A, I → AASS, consonants: S, R, S, W, T → IRWAT Thus, it becomes AASSIRWAT.

Transportation supports the flow of goods from producers to consumers.

In a vertical mirror image, the order of letters reverses from left to right. So “LUCKNOW” becomes “WONKCUL”. It checks spatial reasoning and visualization.

This is a geometric progression with a common ratio of 3. Each term is the previous term multiplied by 3. 81×3 = 243. These patterns are typical in sequence and series problems.

V(22)+A(1)+R(18)+A(1)+N(14)+A(1)+S(19)+I(9) = 104. Each alphabet is converted to its positional number and summed. It’s an arithmetic-based coding pattern.

“My father's wife” = mother (assuming only one wife). Her only daughter = sister of the man. Her son = nephew of the man. But he says “only daughter of my father's wife” → the man is speaking about his own daughter → that child is his son. The relation traced confirms the person is the man's son.

Each letter is replaced by its alphabetical position: U(21), T(20), T(20), A(1), R(18), P(16), R(18), A(1), D(4), E(5), S(19), H(8). Combining gives the correct numerical sequence. This type checks sequential transformation from characters to numbers.

The pattern is: multiply previous term by 2 then subtract 1. 7×2–1 = 13, 13×2–1 = 25, 25×2–1 = 49, 49×2–1 = 97, 97×2–1 = 193. Thus, the missing number before 193 is 97.

P is R’s mother, Q is P’s brother → Q is R’s maternal uncle. T is Q’s father, so T is also P’s father, which makes T the grandfather of R. By tracing relations, T → P → R confirms T is a generation above R. This type of question tests family tree reasoning.

The code pattern adds 3 to the ASCII value of each character of the word. For example, A(65)+3 = D(68), L(76)+3 = O(79). This same rule applies to LUCKNOW → OXEKQVT. This type of question requires pattern recognition based on ASCII shifts.

If Kanpur lies 300 km east of Lucknow, and Varanasi is 200 km further east, then total linear eastward distance from Lucknow to Varanasi is 300 + 200 = 500 km. No angular or alternate path is involved, so the shortest path is the sum. This is a straightforward directional distance-based problem.

Each letter in UTTAR is shifted forward with increasing step sizes: U(+1)=V, T(+2)=V, T(+3)=W, A(+4)=E, R(+5)=W. Then reversed → WEWVV. Same shift and reverse logic applied to PRADESH results in: VYBFJZN. The trick lies in incremental shifting and reversing the result.

The code is based on the position of each letter in the English alphabet (A=1, B=2, ..., Z=26). AGRA = A(1), G(7), R(18), A(1) → 1-7-18-1. It follows the same encoding principle as used in LUCKNOW. No alteration, reverse, or shift is applied, only direct alphabetical positions.

Water ATMs were introduced in Noida to provide clean, affordable drinking water in urban areas. These machines purify and dispense water via smart cards. They help in reducing plastic bottle usage too.

Goods and Services Tax is a dual tax shared by Centre and State.

National database for unorganised workers for future benefits.

A subnet mask identifies the network and host portions of an IP address. It allows efficient routing and management of IP address blocks. Subnetting improves security and performance of networks.

Overfitting occurs when a model learns training data too well, including noise and outliers. It fails to generalize to new data. Techniques like cross-validation and regularization are used to prevent it.

Virtual memory allows a computer to compensate for shortages of physical memory by using disk space. This helps run larger applications by extending RAM virtually. It slows down performance compared to real RAM.

NAND (Not AND) returns false only if all inputs are true. It is considered a universal gate because all logical operations can be built using only NAND gates. It’s essential in hardware design.

A deadlock occurs when processes wait indefinitely for resources held by each other. This creates a circular dependency, halting progress. Operating systems use algorithms to prevent or detect deadlocks.

Pascal is a procedural programming language and not designed for functional programming paradigms. In contrast, Haskell and Scala are purely or partly functional. Python supports functional features but isn’t a functional language by design.

JSON is a lightweight data interchange format based on JavaScript syntax. It's widely used in web APIs and data transmission. It is human-readable and easy to parse by machines.

Due to floating-point precision errors, 0.1 + 0.2 results in a value slightly more than 0.3. Thus, the equality test returns False. This is a classic floating-point arithmetic caveat in computing.

Big Data is defined by its high Volume (data size), Velocity (speed), Variety (types), and Veracity (uncertainty). These characteristics pose challenges for traditional data processing. The 4 Vs guide the design of scalable data systems.

Binary search divides the search space in half with each step, resulting in logarithmic time complexity. It requires the input to be sorted. This makes it faster than linear search for large datasets.

Nonce is a random or pseudo-random number used once in cryptographic communications. In blockchain mining, it's adjusted to find a valid hash. This process ensures block validity in Proof-of-Work systems.

SMTP (Simple Mail Transfer Protocol) is used to send emails from the client to the mail server or between servers. POP3 and IMAP are used for retrieving emails. SMTP typically works on port 25 or 587.
