Classification

Lesson 19 of 113

1. Ye topic hai kya?

Pehle class ka naam bolo (dhatu, phool, planet), phir jo us naam se bahar hai. Leftover tick tab, jab class lock ho.

Odd man out alag: wahan property (prime / square / +2 letter) — class-naam nahi poochha. Yahan category + pair-rishta.

Analogy se farq

Analogy: A:B ka rishta C pe copy. Yahan :: nahi — set mein leftover, lekin pehle class naam.

Odd man se

Wahan 3,5,7,9,11 → 9 not prime. Yahan Copper Iron Gold Wood → class = dhatu, leftover Wood. Same leftover, alag soch.

2. Paper pe dimag kaise chale

Pehle class ka naam, phir leftover:
1) Words — dhatu, phool, planet, weekday, abstract noun, polygon…
2) Numbers — prime / even / ÷n / square / cube
3) Letters — vowel, consecutive, opposite
4) Pairs — har pair ka same rishta (square, auzar-kaam). Jo pair alag rishta rakhe, odd
5) Jo rule sirf ek ko kaate, wahi
Galati: “yeh word mujhe kam aata” tick. Class lock pehle. Do leftover aayein to rule badlo.

3. Word classification

Sabse zyada yahi. Class ek shabd mein bolo, phir jo us shabd se bahar.
