Question

Select the option that represents the letters that when sequentially placed from left to right in the blanks below will complete the letter series.

 _ _ C _ D C _ _ C C _ _

The correct answer is

CDCCDDC

To solve this question, we need to determine the sequence of letters (D and C) that will correctly fill in the blanks to complete the letter series: _ _ C _ D C _ _ C C _ _.

Let's analyze the given options to determine which one fits correctly into the sequence:

  1. Understanding the Pattern: The sequence must be filled with letters from the given options to complete the pattern. The key is to find if there is a repeating segment or logic to naturally complete the sequence.
  2. Checking the Options: We take the option CDCCDDC and place it in the sequence to verify:
    • ​_ _ C _ D C _ _ C C _ _ becomes CDCCDC CDCCC
  3. Verification: By placing C, D, and repeating in the positions provided, the series seems logically consistent with recurring elements D and C which spread evenly across the series, maintaining a rhythm as with many letter pattern problems.

After trying each option, the correct pattern that maintains continuity and rhythm in letter arrangement is, indeed, CDCCDDC.

Therefore, the correct option that completes the letter series is CDCCDDC.

  1. 4 is related to 64 following a certain logic. Following the same logic, 9 is related to 729. To which of the following is 12 related following the same logic?
    (NOTE: Operations should be performed on whole numbers without breaking down the numbers into their constituent digits. E.g., 13 – Operations on 13 such as adding/multiplying, etc., to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
