Question

If 'FRIEND' is coded as 'HUMJTK', how is 'CANDLE' coded?

• A. EDRJRI
• B. EDQJRI
• C. EDSJRI
• D. EDRKRI

Hint:

In letter coding problems, carefully track the shift in alphabetical positions. Often the shift follows a consistent increasing or decreasing pattern.

Answer 1

The Correct Option is A

Concept: In coding–decoding problems, letters are often shifted forward or backward in the alphabet by increasing numerical values.

Step 1: Analyze the pattern in the given coding. FRIEND → HUMJTK \[ F(+2) \rightarrow H \] \[ R(+3) \rightarrow U \] \[ I(+4) \rightarrow M \] \[ E(+5) \rightarrow J \] \[ N(+6) \rightarrow T \] \[ D(+7) \rightarrow K \] Thus, the shift pattern is: \[ +2, +3, +4, +5, +6, +7 \]

Step 2: Apply the same pattern to CANDLE. \[ C(+2) \rightarrow E \] \[ A(+3) \rightarrow D \] \[ N(+4) \rightarrow R \] \[ D(+5) \rightarrow J \] \[ L(+6) \rightarrow R \] \[ E(+7) \rightarrow I \]

Step 3: Write the coded word. \[ \text{CANDLE} \rightarrow \text{EDRJRI} \]
