Question

Select the option that is related to the third in the same way as the second is related to the first.
DEFGH : 4, 5, 6, 7, 8 :: 3, 2, 1, 8, 9 : ?

• A. CBEGI
• B. CBAHI
• C. CDEFG
• D. CDFHG

Hint:

To solve alphabetical coding quickly, memorize the word "EJOTY", where the letters stand for the 5th, 10th, 15th, 20th, and 25th positions.

Answer 1

The Correct Option is B

Concept: This question is based on alphanumeric analogies. It requires mapping each letter of the alphabet to its corresponding numerical position (A=1, B=2, C=3, etc.) and then performing a reverse mapping to find the hidden word.

Step 1: Analyze the first pair (DEFGH : 4, 5, 6, 7, 8).
We check the alphabetical positions of the letters D, E, F, G, and H: D is the 4th letter $\rightarrow$ 4
E is the 5th letter $\rightarrow$ 5
F is the 6th letter $\rightarrow$ 6
G is the 7th letter $\rightarrow$ 7
H is the 8th letter $\rightarrow$ 8 The relationship is a direct 1:1 mapping of alphabetical order.

Step 2: Apply the mapping to the second set (3, 2, 1, 8, 9).
We must find the letters that correspond to these specific numbers: 3rd letter $\rightarrow$ C
2nd letter $\rightarrow$ B
1st letter $\rightarrow$ A
8th letter $\rightarrow$ H
9th letter $\rightarrow$ I

Step 3: Conclusion.
Combining these letters gives us the sequence CBAHI. This matches exactly with Option (B). Final Answer: Option B
