Question

If RUCH is coded as QTBG, then MNOP corresponds to

• A. NOLM
• B. MNOL
• C. LMNO
• D. OLMN

Hint:

In letter coding, analyze the shift pattern between letters carefully and apply the same shift to decode or encode new words.

Answer 1

The Correct Option is C

Step 1: Understand the given coding
RUCH is coded as QTBG. Let us examine the letter shifts from RUCH to QTBG.
Step 2: Analyze letter by letter
- R (18th letter) to Q (17th letter): shift -1
- U (21st letter) to T (20th letter): shift -1
- C (3rd letter) to B (2nd letter): shift -1
- H (8th letter) to G (7th letter): shift -1
Step 3: Apply the same rule to MNOP
M (13th) → L (12th)
N (14th) → M (13th)
O (15th) → N (14th)
P (16th) → O (15th)
Step 4: Write the coded word
MNOP → LMNO.
Step 5: Conclusion
The code for MNOP is LMNO.
