Question

In a certain code the word MISTER is coded as SDUTHN and the word ROWING is coded as HOXXNS. Then in the same code, the word FLIGHT is coded as

• A. UIDSTG
• B. GMDSKT
• C. UIHHMG
• D. GMHHKT

Hint:

In letter coding, always check if the word is reversed first before applying shifts.

Answer 1

The Correct Option is C

Concept: The pattern is based on reversing the word and shifting letters. Rule:
• Reverse the word.
• Shift each letter by \(+1\) or \(-1\) alternately.

Step 1: Observe MISTER → SDUTHN
Word: \[ MISTER \] Reverse: \[ RETSIM \] Applying shifts: \[ R(+1)=S \] \[ E(-1)=D \] \[ T(+1)=U \] \[ S(+1)=T \] \[ I(-1)=H \] \[ M(+1)=N \] Code: \[ SDUTHN \] Matches.

Step 2: Apply same to FLIGHT.
Word: \[ FLIGHT \] Reverse: \[ THGILF \] Now apply: \[ T(+1)=U \] \[ H(+1)=I \] \[ G(+1)=H \] \[ I(-1)=H \] \[ L(+1)=M \] \[ F(+1)=G \] Thus: \[ UIHHMG \] Hence, the code for FLIGHT is: \[ \boxed{UIHHMG} \]
