Question

In a code language BANK is coded as DCPM. Then which word is coded as ECET?

• A. CACR
• B. CACT
• C. CACM
• D. CACP

Hint:

To decode a word when coding uses \(+2\), move every coded letter \(2\) steps backward.

Answer 1

The Correct Option is A

Concept:
From \[ \text{BANK}\rightarrow \text{DCPM} \] the rule is: \[ \text{Each letter is shifted }+2 \] So to decode a coded word, we move each letter \(2\) positions backward.

Step 1: Decode ECET. \[ E\rightarrow C \] \[ C\rightarrow A \] \[ E\rightarrow C \] \[ T\rightarrow R \]

Step 2: Write the original word. \[ \text{ECET}\rightarrow \text{CACR} \]

Step 3: Final answer. \[ \boxed{\text{CACR}} \]
