If "DELHI" is coded as "73541" and "CALCUTTA" as "82589662" using a consistent letter-to-digit mapping, then what is the code for "CALICUT"?

Introduction / Context:Letter–digit substitution with consistency across multiple examples is a staple pattern. We infer the mapping from two given words and reuse it.

Given Data / Assumptions:

• DELHI -> 73541
• CALCUTTA -> 82589662
• Find code for CALICUT.

Concept / Approach:Map each letter to its digit based on the examples. From DELHI we get D->7, E->3, L->5, H->4, I->1. From CALCUTTA we get C->8, A->2, L->5, C->8, U->9, T->6, T->6, A->2.

Step-by-Step Solution:C->8A->2L->5I->1C->8U->9T->6Therefore "CALICUT" becomes 8251896.

Verification / Alternative check:All letters appear in the mapping derived from the two examples; consistency holds.

Why Other Options Are Wrong:

• 5279431 / 5978213 / 8543691: contain digits inconsistent with the deduced mapping at multiple positions.
• None of these: Not applicable since a consistent code exists.

Common Pitfalls:Assuming position-based digits or averaging across examples; here the mapping is letter-specific and fixed.

Final Answer:8251896
