Question

In a certain code language, 'FOAM' is coded as '9618' and 'MUST' is coded as '4536'. What is the code for 'M' in that language?

• A. 4
• B. 5
• C. 3
• D. 6

Answer 1

Answer:

D. 6

We assume each letter has a fixed digit code.

Given:

• FOAM → 9618

• MUST → 4536

Now find the common letter:

The only common letter in both words is M

Check its position:

• FOAM → F O A M → 9 6 1 8 → so M = 8

• MUST → M U S T → 4 5 3 6 → so M = 4

Now we have a conflict (8 and 4).

Key observation:

In such questions, order of digits may not match letter order directly.

Check common digit between both codes:

• 9618 → digits: 9, 6, 1, 8

• 4536 → digits: 4, 5, 3, 6

Common digit = 6

Final Answer: 6
