Question

In a certain code language, 'DEVICE' is coded as 'EDWHDD' and 'DENIAL' is coded as 'EDOHBK'. How will 'DEMAND' be coded in the same language?

• A. EDNBMC
• B. EDNZOC
• C. EDLZMC
• D. EDNBOC

Answer 1

Answer:

B. EDNZOC

Let’s find the pattern letter by letter.

DEVICE → EDWHDD

D → E (+1)
E → D (−1)
V → W (+1)
I → H (−1)
C → D (+1)
E → D (−1)

DENIAL → EDOHBK

D → E (+1)
E → D (−1)
N → O (+1)
I → H (−1)
A → B (+1)
L → K (−1)

Pattern:

Letters at odd positions → +1
Letters at even positions → −1

Apply to DEMAND:

D → E (+1)
E → D (−1)
M → N (+1)
A → Z (−1)
N → O (+1)
D → C (−1)

Final Answer:

EDNZOC
