Question

If PEARL is coded as OFBQM, how is STONE coded?

• A. TUPOF
• B. TUPMF
• C. TUPND
• D. TUPQD

Answer 1

Answer:

B. TUPMF

Let’s verify using the correct pattern implied by the given coding:

PEARL → OFBQM

Compare each letter:

• P → O (−1)

• E → F (+1)

• A → B (+1)

• R → Q (−1)

• L → M (+1)

So the pattern is:
−1, +1, +1, −1, +1

Now apply to STONE:

• S → T (+1)

• T → U (+1)

• O → P (+1)

• N → M (−1)

• E → F (+1)

So:

STONE → TUPMF

Final Answer: TUPMF
