Question

A set of letters and numbers are arranged in certain order where some of them are missing. \[ 1 \quad \_ \quad 7g \quad \_ \quad c8 \quad \_ \quad \_ \quad b \] Choose the correct order of appearing in the missing places.

• A. 3 h a 2
• B. a h 2 3
• C. a 3 h 2
• D. 2 3 h a

Hint:

In alphanumeric series, always check whether letters correspond to their alphabetical positions: \[ a=1,\; b=2,\; c=3,\; \ldots,\; z=26 \] Many reasoning questions are based on this simple relationship.

Answer 1

The Correct Option is C

Concept: The sequence follows the relationship between letters and their corresponding alphabetical positions: \[ a=1,\quad b=2,\quad c=3,\quad d=4,\quad e=5,\quad f=6,\quad g=7,\quad h=8 \]

Step 1: Observe the given pairs The sequence can be grouped as: \[ (1,\_) \quad (7,g) \quad (\_,c) \quad (8,\_) \quad (\_,b) \] Notice that: \[ 7 \leftrightarrow g \] since \(g\) is the 7th letter of the alphabet. Thus, each number is paired with its corresponding letter.

Step 2: Fill the blanks
• \(1\) corresponds to \(a\) \[ \text{Blank 1}=a \]
• \(c\) is the 3rd letter \[ \text{Blank 2}=3 \]
• \(8\) corresponds to \(h\) \[ \text{Blank 3}=h \]
• \(b\) is the 2nd letter \[ \text{Blank 4}=2 \]

Step 3: Write the missing terms in order \[ a,\;3,\;h,\;2 \] Hence, the correct arrangement is: \[ \boxed{a\;3\;h\;2} \] which corresponds to Option (C).
