Question

If MEKLF is coded as 91782 and LLLJK as 88867, then how can IGHED be coded?

• A. 97854
• B. 64521
• C. 53410
• D. 75632

Hint:

When faced with direct coding, solve by eliminating options based on the values of known letters.

Answer 1

The Correct Option is C

Step 1: Read the clues.
MEKLF is coded as 91782 and LLLJK as 88867. We must code IGHED.

Step 2: Match letters to digits.
From MEKLF we get M as 9, E as 1, K as 7, L as 8, F as 2. From LLLJK the three Ls give 8 8 8, then J is 6 and K is 7, which fits K as 7 again.

Step 3: Spot the simple rule.
Look at the gap from each letter to its digit. The position of M in the alphabet is 13 and its code 9, so the difference is 4. Check E, position 5, code 1, difference 4. So each letter equals its alphabet position minus 4.

Step 4: Apply to IGHED.
I is position 9, so 9 minus 4 is 5. G is 7, so 3. H is 8, so 4. E is 5, so 1. D is 4, so 0.

Step 5: Put it together.
That gives the digits 5, 3, 4, 1, 0, which is 53410.

Step 6: Conclusion.
So IGHED is coded as \[ \boxed{53410} \]
