Solving Letter Analogy Questions

This question asks us to find the related letters for 'CELLULAR' based on the relationship shown between 'CHARGER' and 'DGBQHDS'. This type of problem is a letter analogy where a specific pattern or rule transforms the first word into the second. We need to identify this pattern and apply it to the third word to find the answer.

Identifying the Pattern in CHARGER : DGBQHDS

Let's look at the transformation of each letter from CHARGER to DGBQHDS:

• C becomes D
• H becomes G
• A becomes B
• R becomes Q
• G becomes H
• E becomes D
• R becomes S

Now, let's analyze the position change of each letter in the alphabet:

• C to D is moving 1 step forward (\(C \xrightarrow{+1} D\))
• H to G is moving 1 step backward (\(H \xrightarrow{-1} G\))
• A to B is moving 1 step forward (\(A \xrightarrow{+1} B\))
• R to Q is moving 1 step backward (\(R \xrightarrow{-1} Q\))
• G to H is moving 1 step forward (\(G \xrightarrow{+1} H\))
• E to D is moving 1 step backward (\(E \xrightarrow{-1} D\))
• R to S is moving 1 step forward (\(R \xrightarrow{+1} S\))

The pattern identified is a sequence of transformations: +1, -1, +1, -1, +1, -1, +1. The position of the letter in the alphabet is alternately increased by one and decreased by one.

Applying the Pattern to CELLULAR

Now we apply the same +1, -1, +1, -1, +1, -1, +1 pattern to the word CELLULAR:

• C: Apply +1 \(\rightarrow\) D
• E: Apply -1 \(\rightarrow\) D
• L: Apply +1 \(\rightarrow\) M
• L: Apply -1 \(\rightarrow\) K
• U: Apply +1 \(\rightarrow\) V
• L: Apply -1 \(\rightarrow\) K
• A: Apply +1 \(\rightarrow\) B
• R: Apply -1 \(\rightarrow\) Q

Combining the resulting letters, we get DDMKVKBQ.

Comparing with Options

Let's compare our result DDMKVKBQ with the given options:

Our calculated result, DDMKVKBQ, matches Option 1.

Conclusion

The relationship between CHARGER and DGBQHDS follows a specific letter coding pattern of +1, -1, +1, -1, and so on, applied to each letter sequentially. Applying this exact pattern to the word CELLULAR yields DDMKVKBQ. Therefore, DDMKVKBQ is the correct answer.

Additional Information: Types of Letter Coding

Letter coding is a common topic in logical reasoning and competitive exams. Understanding different types of patterns helps solve these problems quickly. Some common types include:

• Shift Coding: Letters are shifted forward or backward by a fixed number of positions (e.g., each letter +2).
• Mixed Shift Coding: The shift pattern varies for each letter or follows a sequence (like the +1, -1 pattern here).
• Reverse Order Coding: The letters of the word are written in reverse order, sometimes with a shift.
• Alphabet Position Coding: Letters are coded based on their numerical position in the alphabet.
• Opposite Letter Coding: Each letter is replaced by its opposite letter (e.g., A is opposite Z, B is opposite Y).

Practicing these different types of coding helps in quickly identifying the rule in a given analogy problem.
