Classification - English alphabet
Introduction
Classification involves identifying the 'odd man out' from a given set of options. In English alphabet classification, students must find the group that does not follow the common logic shared by others.
Explanation Step by Step
To solve these problems quickly, you must memorize the position of each letter from both the left (forward) and right (backward) sides.
| Letter | N | O | P | Q | R | S | T | U | V | W | X | Y | Z |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Left Position | 14 | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 | 24 | 25 | 26 |
| Right Position | 13 | 12 | 11 | 10 | 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 |
Sub-topics
English Alphabet
This sub-topic focuses on sequences, vowel-consonant logic, and numerical positions of letters.
Examples
Example 1
Options: DF, GI, JL, MO. D(+2)=F, G(+2)=I, J(+2)=L, M(+2)=O. All follow +2 pattern. Let's try another logic like vowel presence.
Logic: Pattern of gaps between letters.
Tricks and Shortcuts
Use the formula: Left Position + Right Position = 27. If you know the left position, subtract it from 27 to get the right position.
Common Mistakes
Not checking for the reverse letter pairs (e.g., A-Z, B-Y, C-X).
