It is classified mainly into three sections

1. Alphabets
2. Numbers
3. Words

Single alphabets:

If single alphabets are given, then you should follow the order of checking 

1. Vowels first
2. mirror images
3. water images
4. Place values, so that you may get any clues with the number assiciated with that specific alphabet.

Alphabet Groups

1. Alphabetical order of given alphabets
2. Distance / Gap between the given alphabets
3. Vowel / Consonant differences

Pick the odd one out

Answer:

Explanation:

First check the alphabetical order, but we can't find anything there.

Then try GAPS, 

A 4 F 1 H

A 6 H 3 L

A 8 J 2 M

A 16 R 4 W

A 12 N 3 R

But no clue.

Try adding the numbers we got in gaps,

4+1 = 5

6+3 = 9

8+2 = 10

16+4 = 20

12+3 = 15

But no clue.

Subtract the numbers,

4-1 = 3

6-3 = 3

8-2 = 6

16-4 = 12

12-3 = 9

Again no clue.

Multiply the numbers

4 X 1 = 4

6 X 3 = 18

8 X 2 = 16

16 X 4 = 64

12 X 3 = 36

All numbers except 18 are square numbers. So option b is the Odd one.

Pick the odd one out

Answer:

Explanation:

Here AE are the only vowels in the given option. So there is a tendency to choose Option a as their answers. BUT, according to our order given above, we should first check for the alphabetical order... no clue..... later GAP. Check the difference fro Ato E and G to M ....

AbcdE

GhijklM

MnopQ

VwxyZ

LmnoP

Here, except the second pai all others are having 3 letters in between the given alphabets. But the second pair have 5 alphabets between G and M. So the answer is Option b (not Option a).

Pick the odd one out

Answer:

Explanation:

Check the Order : ABC... BCD... CDE... DEF... EFG...Here all alphabets are in an order.. So we cant find out the Odd one with this logic. 

Next, check the Gap : All alphabets have equal number differences / Gaps. So this technique too of no use.

Then, check for the Vowels. 

• In option 1, One vowel is there (A)
• In option 2 No vowel
• In option 3, One vowel is there (E)
• In option 4, One vowel is there (E)
• In option 5, One vowel is there (E)

So, the answer is Option 2, ie. BCD

Pick the odd one out

Answer:

Explanation:

Here the answer is H because the difference between the alphabets is 2.
