Question

If in a certain code, "COLD" is written as "DPME", then how is "HEAT" written?

• A. IFBU
• B. IDBU
• C. IFBS
• D. JGBU

Hint:

In coding-decoding problems, look for consistent shifts or changes between corresponding letters in the word and its code.

Answer 1

The Correct Option is A

The code applies a Caesar cipher with a shift of +1 to each letter. For example:
- C becomes D
- O becomes P
- L becomes M
- D becomes E

When this rule is applied to "HEAT":
- H becomes I
- E becomes F
- A becomes B
- T becomes U

Therefore, the encoded form of "HEAT" is "IFBU".

Answer: \(\boxed{A}\)
