ALPHA-NUMERIC-SYMBOL TEST (Part-I)

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)
