Project Tiger was launched to conserve Bengal Tigers and their habitats.

Pure rainwater is neutral (pH 7), but acid rain has lower pH due to pollution.

Drip irrigation saves water by delivering it directly to plant roots.

Sound intensity is measured in decibels (dB); >85 dB is harmful.

Incomplete combustion in engines releases toxic CO gas.

CO₂ traps heat in the atmosphere, leading to global warming.

: Western Ghats is one of the 36 global biodiversity hotspots.

: An electric motor uses electricity to create motion.

Matchsticks contain sulphur for ignition.

CO₂ reacts with limewater (calcium hydroxide) forming calcium carbonate.

WBCs are the immune cells that defend the body against infections.

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.

It is a geometric progression: each number is multiplied by 2. 64×2 = 128. It tests pattern recognition under multiplication.

Commerce bridges the gap between producers and consumers.

Liability of members is limited to their shareholding.

An entrepreneur starts and runs a business, often with innovation and risk.

It is the simplest and oldest form, owned and controlled by one person.

Profit is the core objective for sustainability and growth in business.

Each letter is replaced with its reverse alphabet value (A=Z, B=Y, C=X,...). R→I, A→Z, E→V, B→Y... etc. Using this transformation gives IZVYIZOVR. This is a complex letter-replacement reasoning type.

Lucknow, Kanpur, and Varanasi are cities in UP, while Yamuna is a river. It is the only non-urban entity among the options. Odd-one-out questions often use thematic categorization.

Vowels (A, E, U) → next alphabet = B, F, V. Consonants → previous alphabet (T→S, P→O, R→Q, etc.). After substitution, we get: VSSBQ QSBDEFT.

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.
