Question

In a certain code SHIP is coded as TJLT and BOAT is coded as CQDX, then in the same code, PLANE is coded as

• A. QMESK
• B. QPFTL
• C. QRGVM
• D. QNDRJ

Hint:

In letter shifting coding, always check whether the increment increases position-wise.

Answer 1

The Correct Option is D

Concept: Observe the pattern carefully. Each letter is shifted forward by increasing values. Pattern: \[ +1,\;+1,\;+3,\;+4,\;+5 \]

Step 1: Verify SHIP → TJLT
\[ S \to T \quad (+1) \] \[ H \to J \quad (+2) \] \[ I \to L \quad (+3) \] \[ P \to T \quad (+4) \] Matches.

Step 2: Verify BOAT → CQDX
\[ B \to C \quad (+1) \] \[ O \to Q \quad (+2) \] \[ A \to D \quad (+3) \] \[ T \to X \quad (+4) \] Matches.

Step 3: Apply to PLANE.
\[ P \to Q \quad (+1) \] \[ L \to N \quad (+2) \] \[ A \to D \quad (+3) \] \[ N \to R \quad (+4) \] \[ E \to J \quad (+5) \] Thus: \[ QNDRJ \] Hence, the code for PLANE is: \[ \boxed{QNDRJ} \]
