Question

If A1B3C5D7E9 is coded as B2C4D6E8F0, how is M3N5O7P9 coded in the same way?

• A. N4O6P8Q0
• B. N4O6P8Q1
• C. L4M6N8O0
• D. N4O6P8R0
• E. O5P7Q9R0

Answer 1

The Correct Option is A

Concept: Mixed coding (letters and numbers both change).
Step 1: Analyze letter pattern.} Each letter shifts forward by +1 (A→B, B→C, etc.)
Step 2: Analyze number pattern.} Each number increases by +1 (1→2, 3→4, etc.), and 9→0.
Step 3: Apply to M3N5O7P9.} M→N, 3→4; N→O, 5→6; O→P, 7→8; P→Q, 9→0
Step 4: Form the code.} N4O6P8Q0
