Question

In a certain code language, 'MARKET' is written as 'NBSLFU'. How is 'BRAND' written in that code?

• A. CSBOE
• B. CSBME
• C. ASBME
• D. CTBOE

Hint:

Convert both the sample word and its code into numeric alphabet positions and look for a constant add-on value between them, then reapply that same number to the new word.

Answer 1

The Correct Option is A

Step 1: Convert the code pair MARKET to NBSLFU into alphabet position numbers: M=13, A=1, R=18, K=11, E=5, T=20 become N=14, B=2, S=19, L=12, F=6, U=21.
Step 2: Compute the numeric shift for each letter: $14-13=1$, $2-1=1$, $19-18=1$, $12-11=1$, $6-5=1$, $21-20=1$. Every letter's code value equals (original value $+\,1$).
Step 3: Apply the rule "code value = original value + 1" to BRAND: B=2 to 3=C, R=18 to 19=S, A=1 to 2=B, N=14 to 15=O, D=4 to 5=E.
Step 4: Reading the new numeric values 3, 19, 2, 15, 5 back as letters gives C, S, B, O, E, i.e. CSBOE.
Step 5: The remaining options each break this consistent +1 numeric shift on at least one letter, so they are eliminated.
Correct option: CSBOE
