Classification Reasoning: Easy Study Material with Emojis

What is Classification? 🧐

Classification means grouping items based on a common quality and spotting the one that doesn’t fit—the “odd one out.” These questions can involve words, letters, numbers, or figures. Your task is to find the item that is different from the rest based on a hidden logic or property¹².

Types of Classification Questions

1. Odd Word Out 📝

You are given four words. Three have something in common, one is different. Find the odd one!

Examples:

• 🍐 Pear
• 🍏 Apple
• 🍈 Guava
• 🍊 Orange Answer: Orange (it’s a citrus fruit, others are not)
• 🍅 Tomato
• 🍆 Brinjal
• 🥒 Cucumber
• 🥔 Potato Answer: Potato (grows underground, others grow above ground)

Tip: Look for categories, uses, or features that unite three and exclude one.

2. Odd Pair of Words 👬

Here, you get pairs of words. Three pairs share a relationship, one pair is different.

Examples:

• Gold : Ornaments
• Cloth : Garments
• Leather : Footwear
• Earthen pots : Clay Answer: Earthen pots : Clay (in other pairs, the first is the raw material for the second, but here, the second is the raw material for the first)
• Broad : Wide
• Light : Heavy
• Tiny : Small
• Big : Large Answer: Light : Heavy (others are synonyms, this is an antonym pair)

3. Odd Letter Group 🔤

Find the group of letters that doesn’t follow the pattern of the others.

Examples:

• H
• Q
• T
• Z Answer: Q (others are in even-numbered positions in the alphabet)
• GE
• MK
• WU
• QN Answer: QN (difference in their letter positions is 3, others have a difference of 2)

4. Odd Number / Pair of Numbers 🔢

Find the number or pair that doesn’t fit the pattern.

Examples:

• 2
• 32
• 56
• 128 Answer: 56 (others are powers of 2)
• 144
• 169
• 256
• 288 Answer: 288 (others are perfect squares)
• 57
• 87
• 131
• 133 Answer: 131 (it’s a prime, others are not)

5. Odd Figure Out 🔲

Given a set of figures, pick the one that is different.

Example: If three figures are mirror images and one is not, pick the different one.

How to Solve Classification Questions? 🧠

• Step 1: Look for what three items share (category, function, shape, etc.).
• Step 2: Check the odd one for a different property.
• Step 3: For numbers, check for mathematical patterns (primes, squares, cubes, etc.).
• Step 4: For letters, look for positions in the alphabet or patterns.
• Step 5: For figures, check for symmetry, rotation, or unique features.
