Question

Find the alternative which will replace the question mark.
BFNM : EIQP :: RBGJ : ?

• A. GHJK
• B. WXYZ
• C. UEJM
• D. ABCD
• E. PQRS

Hint:

When all letters shift by the same numerical value, it is a simple Caesar Cipher. Quickly check the first and last letters to confirm the shift.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Determine the alphabetical shift between the first pair and apply it to the second pair.
Step 2: Identifying the Vector of Change:
Compare BFNM to EIQP: - B $\rightarrow$ E ($+3$) - F $\rightarrow$ I ($+3$) - N $\rightarrow$ Q ($+3$) - M $\rightarrow$ P ($+3$) The pattern is a consistent $+3$ shift for every letter.
Step 3: Calculation:
Apply $+3$ to RBGJ: - R $+ 3 = $ U - B $+ 3 = $ E - G $+ 3 = $ J - J $+ 3 = $ M
Step 4: Final Answer:
The resulting code is UEJM. Thus, the correct option is (c).
