Q. In a certain code language ‘over and above’ is written as ‘da pa ta’ and ‘old and beautiful’ is written as ‘sa na pa;. How is ‘over’ written in that code language?

Explanation by: Indresh Gehalot

Here's how to solve this code language problem:
 * Identify the common word:
   * The common word in both phrases is "and".
   * The common code word in both coded phrases is "pa".
   * Therefore, "and" is coded as "pa".
 * Analyze the remaining words:
   * "over and above" is coded as "da pa ta".
   * "old and beautiful" is coded as "sa na pa".
   * Now we know “and” = “pa”.
   * So "over above" = "da ta"
   * And “old beautiful” = “sa na”
 * Determine the code for "over":
   * Since "over" is one of the remaining words in "over and above," its code must be either "da" or "ta".
   * However, we don't have enough information to determine which one is the correct code.
Therefore, the answer is (D) da or ta.
