Question

In a certain code language, 'BORDER' is coded as 'OBDRRE' and 'BEYOND' is coded as 'EBOYDN'. How will 'BURDEN' be coded in the same language?

• A. UBDREN
• B. NEDRUB
• C. UBRDNE
• D. UBDRNE

Answer 1

Answer:

D. UBDRNE

Given:

BORDER → OBDRRE
Positions:

• B → O

• O → B

• R → D

• D → R

• E → R

• R → E

This is just pairwise swapping of letters:

• 1st ↔ 2nd

• 3rd ↔ 4th

• 5th ↔ 6th

Check with second word:

BEYOND → EBOYDN

• B ↔ E → EB

• Y ↔ O → YO

• N ↔ D → DN

Apply the same rule to BURDEN

Letters: B U R D E N

Swap pairs:

• B ↔ U → UB

• R ↔ D → DR

• E ↔ N → NE

BURDEN → UBDRNE
