Classification Questions

• Choose the odd number: In 143, 257, 195, and 15, three are composite, while one is prime. Identify the prime number.
• Identify the odd term: Three of the following are birds, while one is a mammal that flies. Choose the non-bird.
• Choose the odd term: Fruit, Flower, and Leaf are plant parts; Tree is an entire plant. Identify the outlier.
• Identify the odd number: Among 39, 69, 57, and 117, exactly one is a multiple of 19. Choose that number.
• Choose the odd term: Tree, Plant, and Shrub are categories/types of vegetation, whereas Farm is a place where plants are cultivated. Identify the outlier.
• Identify the odd item: Three are basic stationery tools for writing/erasing (Pencil, Eraser, Sharpener). One is an electronic computation device. Choose the outlier.
• Choose the odd number: 17, 19, and 23 are primes. One number is composite. Identify the composite number.
• Identify the odd pair: Three pairs express a relation of increasing intensity (mild action/state → stronger one): Flurry→Blizzard, Moisten→Drench, Prick→Stab. One pair does not represent the same intensity relation. Choose the mismatching pair.
• Choose the odd term: Thyroxine, Adrenaline, and Insulin are hormones; Iodine is a chemical element (nutrient), not a hormone. Identify the outlier.
• Identify the odd pair: Three pairs are antonyms (Dim–Bright, Wrong–Right, Shallow–Deep). One pair consists of synonyms (same/near meaning). Choose the synonym pair.
• Classification – Odd one out (relationship type) Each pair shows a relation between two objects. Three pairs follow the whole–part relation (object → its component), while one pair shows an instrument → product relation. Identify the pair that does not follow the whole–part pattern.
• Classification – Odd one out (synonym vs antonym) Each pair relates two words. Three pairs are antonyms or complementary opposites, whereas one pair is a clear synonym set. Identify the synonym pair as the odd one out.
• Classification – Odd one out (product vs category) Three pairs show fruit/vegetable → processed product (e.g., jam, squash, puree). One pair shows item → category (hyponym → hypernym). Identify the odd relation.
• Classification – Odd one out (food vs habitat) Three pairs are animal → typical food; one pair is animal → typical place (habitat/setting). Identify the pair that does not follow the food relationship.
• Classification – Odd one out (alphabetic jumps) Each string consists of 3 letters. In three strings, the jumps are +2 then +3 in alphabet positions; in one string, the second jump deviates. Identify the deviating string.
• Classification – Odd one out (constant +6 jumps) Four 3-letter strings are tested for uniform alphabet jumps. In three strings, both jumps are +6; one string breaks this pattern. Identify the odd one.
• Classification – Odd one out (letter–letter with numeric mean) In these alphanumeric items, the number equals the average (arithmetic mean) of the alphabet positions of the two letters. Three items follow this rule; one does not. Identify the exception.
• Classification – Odd one out (paired vs unpaired body parts) Among these body parts, three normally occur as paired organs in humans; one is not typically paired. Identify the odd one out.
• Classification – Odd one out (tool → object of action) Three pairs name a tool and the typical object it acts upon. One pair names two similar stationary items rather than a tool–target relation. Identify the odd pair.
• Classification – Odd one out (letter sequences with growing gaps) Four 5-letter sequences are examined. Three progress with increasing step sizes +2, +3, +4, +5. One sequence breaks this growth pattern. Identify the odd sequence.
