Question

In a certain code language KNIFE is written as MRKJG. How is DOCTOR written?

• A. FDDXQV
• B. FSEXRV
• C. FSEXQU
• D. FSEXQV

Hint:

If a coding pattern involves position-based shifts, write the shift sequence separately and apply it systematically to each letter of the new word.

Answer 1

The Correct Option is D

Concept: From \[ KNIFE \rightarrow MRKJG \] we observe the pattern: \[ +2,\ +4,\ +2,\ +4,\ +2 \] on successive letters.

Step 1: Apply the same pattern to DOCTOR.
\[ D+2=F \] \[ O+4=S \] \[ C+2=E \] \[ T+4=X \] \[ O+2=Q \] \[ R+4=V \]

Step 2: Combine the coded letters.
\[ DOCTOR \rightarrow FSEXQV \] Therefore, the required code is \[ \boxed{\text{FSEXQV}} \]
