Question:

In a certain code language, 'LAMP' is coded as 'IWJL'. What is the code for 'LOGS' in that code language?

Options:

  1.   IKDP
  2.   IJDO
  3.   IKEO
  4.   IKDO

Answer:

Option 4: IKDO

Explanation:

Let's analyze the given code:

 * LAMP is coded as IWJL.

If we observe the alphabetical positions of the letters, we can see a pattern:

 * L (12th letter) is coded as I (9th letter), which is 3 letters before.

 * A (1st letter) is coded as W (23rd letter), which is 22 letters before.

 * M (13th letter) is coded as J (10th letter), which is 3 letters before.

 * P (16th letter) is coded as L (12th letter), which is 4 letters before.

So, the pattern is:

 * The first letter is coded as the letter 3 positions before.

 * The second letter is coded as the letter 22 positions before.

 * The third letter is coded as the letter 3 positions before.

 * The fourth letter is coded as the letter 4 positions before.

Applying this pattern to the word "LOGS":

 * L (12th letter) becomes I (9th letter)

 * O (15th letter) becomes K (11th letter)

 * G (7th letter) becomes D (4th letter)

 * S (19th letter) becomes O (15th letter)

Therefore, the code for "LOGS" is IKDO.
