Logical Reasoning(Master ) Alpha-Numeric Series

Directions: Read the following alphanumeric series carefully and answer the questions given beside.

O 8 F # 4 @ M 2 E Q % R T & 6 Z * N S $ 7 A
Step 1: If a symbol is immediately preceded and followed by a letter then write it between 6 and Z.
Step 2: If a number is immediately preceded by a symbol and immediately followed by a letter then write it between M and 2.
Note: Step 2 is performed after completion of step 1.

Explanation:

Sequence after step 1:
O 8 F # 4 @ M 2 E Q R T & 6 % * Z N S $ 7 A
The new sequence after dropping all the vowels:
8 F # 4 @ M 2 Q R T & 6 % * Z N S $ 7
Only one number is there which is immediately preceded by a letter.
Hence option 1 is correct.
Sequence after step 1:
O 8 F # 4 @ M 2 E Q R T & 6 % * Z N S $ 7 A
Sequence after step 2:
O 8 F # 4 @ M 7 2 E Q R T & 6 % * Z N S $ A
Common Explanation:
Given Sequence:
O 8 F # 4 @ M 2 E Q % R T & 6 Z * N S $ 7 A
Step 1: If a symbol is immediately preceded and followed by a letter then write it between 6 and Z.
Sequence after step 1:
There are two symbols which are immediately preceded and followed by a letter which are - % and *
O 8 F # 4 @ M 2 E Q R T & 6 % * Z N S $ 7 A
Step 2: If a number is immediately preceded by a symbol and immediately followed by a letter then write it between M and 2.
Sequence after step 2:
There is only one number '7' which is immediately preceded by a symbol '$' and immediately followed by letter 'A'.
O 8 F # 4 @ M 7 2 E Q R T & 6 % * Z N S $ A
