# Letter Odd Man

In problems on letter odd man, four groups of letters are normally given, out of which three groups are based on the same rule or pattern and the remaining one is different. The groups of letters are referred to as

While analysing the pattern or rule followed by the group of letters (terms), the following aspects may be taken into consideration.

*terms*. The terms need not necessarily form words. Normally, the terms are to be treated as just a set of letters and the pattern or rule followed by them is to be analysed. Students are required to identify the term which is different from the rest of the terms. In some problems, the terms may be in the form of words. While analyzing such problems, the meaning conveyed by the words or arrangement of letters in the words, or both these aspects, may have to be considered.While analysing the pattern or rule followed by the group of letters (terms), the following aspects may be taken into consideration.

- Position of the letters in each group.
- Missing number of letters in each group.
- Order of letters (forward or reverse order).
- Number of vowels in the group.
- Position of vowels in the group.
- Anagrams.
- Repetition of letters.
- Combination of corresponding letters (CL), alternate letters, consecutive letters, etc.

# Examples

Example-1

- G F E D C
- O N M L K
- J I H G F

**Answer:**(3) L J N P R

Example-3

- F T G S P
- A Z B Y C
- H S I R J
- C X D W E

Solution

In all the terms except in (1), the letters at positions 1, 3 and 5 are consecutive letters.
The letters at positions 2 and 4 are corresponding letters of the letters at positions 1 and 3, respectively.

**Answer:**(1) F T G S P

Example-4

- A D G J
- L O R U
- P S V Y
- H K N P

Solution

In all the terms except in (4), two letters are skipped between the letters at consecutive positions.

**Answer:**(4) H K N P

Example-5

- E C F G I
- J H K N L
- Q O R U S
- X V Y B Z

Solution

In all the terms except in (1), the letters at positions 1, 3 and 5 are consecutive.
The letters at positions 2 and 1 as well as at positions 5 and 4 are alternate.

**Answer:**(1) E C F G I

Example-6

- P R O Q N
- D F C E G
- K M J L I
- M O L N K

Solution

In all the terms except in term (2), the letters at positions 5, 3, 1, 4 and 2 are consecutive.
In term (2), the letters at positions 3, 1, 4, 2 and 5 are consecutive.

**Answer:**(2) D F C E G

Example-7

- C E H L Q
- S U X B G
- H J M Q V
- N P S W C

Solution

In all the terms except in (4), the number of letters missing between the letters in consecutive positions is in the increasing order.
One letter is skipped between the letters at positions 1 and 2.
Two letters are skipped between letters at positions 2 and 3.
Three letters are skipped between letters at positions 3 and 4.
Four letters are skipped between letters at positions 4 and 5.
However, in term (4), five letters are skipped between letters at positions 4 and 5.

**Answer:**(4) N P S W C

Example-8

- G E H D I J
- C A D Z E G
- X V Y U Z A
- D B E A F G

Solution

The letters at positions 4 and 2 are consecutive.
Further, one letter is skipped between the letters at positions 2 and 1.
In all the terms except in (2), the letters at positions 1, 3, 5 and 6 are consecutive.

**Answer:**(2) C A D Z E G

Example-9

- N
- H
- F
- M

Solution

Each term contains a single letter.
All letters except (M) can be formed using 3 straight line segments, whereas 4 straight line segments are required to construct M.

**Answer:**(4) M

Example-10

- C A T
- M A T
- E A T
- F A T

Solution

In this problem, each term forms a word.
The words â€˜CATâ€™, â€˜MATâ€™ and â€˜FATâ€™ have only one vowel, but the word â€˜EATâ€™ has two vowels.

**Answer:**(3) E A T

Example-11

- B A T
- D E A R
- L E V E L
- M O O N

Solution

The third word is a PALINDROME

(The word which remains unchanged when read backwards, i.e., from right to left, is called a PALINDROME).
But other words are not PALINDROME.

(The word which remains unchanged when read backwards, i.e., from right to left, is called a PALINDROME).

**Answer:**(3) L E V E L

Example-12

- R U A M B
- Y G P T E
- A I C N H
- E I H D L

Solution

This problem is based on ANAGRAM (where the letters of a word is jumbled).
Term (1) is the anagram of B U R M A.
Term (2) is the anagram of EGYPT.
Term (3) is the anagram of CHINA.
Term (4) is the anagram of DELHI.
So, the fourth term represents a city, whereas the other terms represent the countries.
