Sitting Arrangement Examples

Example of Sitting Arrangement
Six friends – Arun, Senthil, Praveen, Bharani, Avinnash, Karthik – are standing straight line facing North but not necessarily in same order.
  1. Arun is standing Fourth to the left of Karthik.
  2. Senthil is standing Second to the right of Bharani.
  3. Praveen is standing second to the right of Senthil.
  4. Karthik is not standing of the extreme end of this line.
Totally Six positions in a Straight Line. All are facing North.
When taking the first condition alone, we get two chances. That is Arun may either come in First Position or in Second Position. Based on Arun’s position Karthik may either come in 5th or 6th position. See Condition 4. Karthik is not in extreme end. So that make Karthik to come in V position and Arun in I position.
Arun – _____ – _____ – ______ – Karthik -______.
Now Condition 2. Senthil can come in position 4 or position 6. Assume he comes in position 6.
Arun – _____ – ______ – Bharani – Karthik – Senthil.
Our assumption is wrong. Because according to Statement 3, Praveen is standing to the right of Senthil.
So that makes Senthil to come in Place 4.
Arun – Bharani – _____ – Senthil – Karthik – Praveen.
The remaining place (3rd position) is for Avinnash.
Arun – Bharani – Avinnash – Senthil – Karthik – Praveen.
