Question

Find out missing letters in the given series
KPA, LQB, MRC, NSD, (____)

• A. TOE
• B. OET
• C. ETO
• D. OTE

Hint:

Write down the alphabet on scratch paper during the exam to quickly track positions. In this question, all three series are simply consecutive letters (+1 shift).

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
In letter series questions, each term consists of multiple letters.
We analyze the alphabetical progression of each letter position (first, second, and third letters) separately across consecutive terms.

Step 2: Detailed Explanation:
Let us list the terms and analyze each letter position:
Terms:
\[ \text{1. KPA, \quad 2. LQB, \quad 3. MRC, \quad 4. NSD} \]
1. First letter of each term:
- K \(\rightarrow\) L \(\rightarrow\) M \(\rightarrow\) N
The pattern is a direct progression of consecutive letters in alphabetical order:
\[ \text{N} + 1 = \text{O} \]
2. Second letter of each term:
- P \(\rightarrow\) Q \(\rightarrow\) R \(\rightarrow\) S
This is also a direct progression of consecutive letters in alphabetical order:
\[ \text{S} + 1 = \text{T} \]
3. Third letter of each term:
- A \(\rightarrow\) B \(\rightarrow\) C \(\rightarrow\) D
This is also a direct progression of consecutive letters in alphabetical order:
\[ \text{D} + 1 = \text{E} \]
Combining the determined letters gives:
\[ \text{O} + \text{T} + \text{E} = \text{OTE} \]
This matches Option D.

Step 3: Final Answer:
The missing term in the series is OTE.
