Question

If the word 'LEADER' is coded as 20-13-9-12-13-26. How would you write "LIGHT"?

• A. 20-16-15-17-22
• B. 20-17-15-16-28
• C. 20-15-16-18-23
• D. 20-16-17-15-27

Hint:

Always write down the alphabetical positions first. If the code starts with a higher number than the letter's position, check for a constant addition or a reverse alphabet pattern.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
In coding-decoding, we identify the numerical position of each letter in the English alphabet (A=1, B=2, ..., Z=26) and find the mathematical operation applied to it.

Step 2: Key Formula or Approach:
Pattern: $\text{Code} = \text{Alphabetical Position} + 8$.

Step 3: Detailed Explanation:
Check for 'LEADER':
• L (12) + 8 = 20
• E (5) + 8 = 13
• A (1) + 8 = 9
• D (4) + 8 = 12
• E (5) + 8 = 13
• R (18) + 8 = 26 Applying the same to 'LIGHT':
• L (12) + 8 = 20
• I (9) + 8 = 17
• G (7) + 8 = 15
• H (8) + 8 = 16
• T (20) + 8 = 28 Wait, re-checking the provided options against the calculation: If we look at option (B) 20-17-15-16-28, it matches our logic perfectly. (Note: Looking at the user options provided, option B matches the logic).

Step 4: Final Answer:
Following the $+8$ logic, "LIGHT" is written as 20-17-15-16-28.
