Answer 1

Answer:

blue

Explanation:

as we know there are 5 chairs . so we assume person wearing red shirt sits on the 2nd chair and person wearing blue shirt sits on the 1st chair . also we know that the person wearing green shirt is sitting on the one extreme end and the distance between the person wearing blue shirt and green shirt is same , so person wearing black shirt is sitting on the middle chair(3rd chair) . so automatically we come to know that person wearing blue shirt is sitting on the extreme left end.
