In this topic, a JUMBLED SEQUENCE of some Alphabets / Letters / Numbers / Symbols are given, followed by Certain Questions based on It.

Now Lets See the BASICs of It.

BASICS :
  • Before starting with this topics lemme clear some Meanings of the words "Following, Followed by, Preceding and Preceded by" Let me start with an example.
    • Take Two consecutive alphabets (say A B), Here
      • A is Preceding B <=> B is Preceded by A
      • B is Following A <=> A is Followed by B
    • Take One more Example. Now take 3 consecutive alphabets (say ABC), Here
      • A is followed by B and C, But
        • A is immediately followed by B,
        • A is not immediately followed by C      (Or We can say)
        • A is not immediately followed by C
        • A is followed by C, but NOT immediately.
      • C is preceded by A and B, But
        • C is immediately preceded by B,
        • C is not immediately preceded by A   (Or We can say)
        • C is preceded by A but not Immediately
Now Lets see some EXAMPLES
  • How many such Numbers are there in the arrangement each of which is immediately followed by a Symbol and also immediately preceded by a Consonant?
    • Sol : Check for the sequence of Consonant-Number-Symbol (Shortcut : just write the first letters CNS above the question and check for that arrangement)
  • How many such Consonants are there in the arrangement each of which is immediately preceded by a Number and also immediately followed by another Consonant?
    • Sol : Check for the sequence of Number - Consonant - Consonant (Shortcut : Same as above. write NCC n check)
  • How many such Symbols are there in the arrangement each of which is immediately preceded by a Number but NOT immediately followed by a Vowel?
    • Sol: Check for the sequence of  Number - Symbol - Not Vowel (Shortcut: Write NSV (Just strike the letter V (or u can put the TICK marks above the letters N and S)
  • How many such Numbers are there in the arrangement each of which is not immediately followed by a Letter and not Immediately preceded by a Symbol?
    • Sol: Check for the sequence of no Symbol - Number - no Letter (SNL)
  • How many such Symbols are there in the arrangement each of which is Either Immediately preceded by a Number or immediately followed by a Consonant but not both?
    • Sol: Check for the sequence of Number - Symbol / Symbol - Consonant (NS or SC)
  • How many such Consonants are there in the arrangement each of which is either immediately preceded by a Number or immediately followed by a Symbol or Both?
    • Sol: Check for the sequence of Number - Consonant / Consonant - Symbol / Number - Consonant - Symbol (NC or CS or NCS)
