Key Points at a Glance

  1. 1

    The 2026 CET Senior Secondary syllabus places Code and decode and Sitting arrangement inside Logical Reasoning and Mathematics, so this topic must stay focused on puzzle structure, placement and rule testing.

  2. 2

    Linear seating questions test position, direction and order; the safest first step is to mark whether the row faces north, south or an unknown direction.

  3. 3

    In a row facing north, a person's left is the candidate's left on paper, but in a row facing south the left and right reverse.

  4. 4

    Circular seating questions become easier after fixing one person, because rotation changes the drawing but not the real arrangement.

  5. 5

    In a circular arrangement where all persons face the centre, left usually moves clockwise and right anticlockwise from that person's view; outside-facing persons reverse this.

  6. 6

    Code-decode questions ask you to identify the rule that changes a word, letter group, number or symbol pattern into another form.

  7. 7

    The safest code-decode method is to compare positions, gaps, reversal, pairing and digit operations before choosing an answer.

What seating arrangement and code-decode questions test

Seating arrangement is a placement problem. The question gives persons, seats and clues, then asks the candidate to find a position, neighbour, direction or pair. The 2026 CET Senior Secondary syllabus lists "Sitting arrangement" under Logical Reasoning and Mathematics, so the exam focus is not advanced mathematics; it is the ability to convert sentences into slots and keep every clue visible until the final answer is checked. At this level, the arrangement is usually linear, circular, or a small mixed order such as persons sitting around a table.

Code-decode is a rule-finding problem. The 2026 syllabus separately lists "Code and decode" in the same reasoning-mathematics block. The question gives an original word, letter group, number or symbol pattern and its coded form, then asks the candidate to apply the same rule to another item. The rule may shift letters forward or backward, reverse the order, pair first and last letters, replace letters by their alphabet positions, or combine numbers by a simple operation. Seating arrangement and code-decode look different, but both reward the same exam habit: write the structure on paper before touching the options.

Rajasthan names such as Jaipur, Kota or Ajmer may appear in examples, but they are only labels unless the question itself asks for state knowledge. In a seating question the rule is about placement; in a code-decode question the rule is about transformation.

Core rule: do not keep the puzzle fully in the head; draw slots for seating and write the coding rule step by step for code-decode.
