They belong to different states Bihar, Punjab, J&K. Rajasthan, West Bengal.Odisha, Tamil Nadu and Haryana but not necessarily sitting in the same order. Six people out of 8 are Engineers and remaining two are Doctors. If two people are sitting on consecutive seats, then only they will be considered neighbors.
Six of these 8 people have only one neighbor. One doctor has 2
neighbors and the other has only one neighbor. No one is sitting
between the ones from Punjab and Haryana. A is sitting equidistant from both the ones from Bihar and Haryana. Similarly G is sitting equidistant from both the one from J&K and F. H is sitting to the immediate left of E. A is sitting to the immediate left of the one from Punjab. C is from West Bengal and is a doctor having only one neighbor. F belongs to Odisha . E, who is an Engineer, is from Tamil Nadu. D is not from Punjab and A is not from Rajasthan.The sum of seat numbers on which the ones from
Haryana and Punjab are sitting is 12.​

Answer 1

Answer:

No one is sitting between the ones from Punjab and Haryana. The sum of seat numbers on which the ones from Haryana and Punjab are sitting is 12. This gives only seat nos 5 and 7.

Now since A is left of Punjab so Punjab cannot be on 7. So Punjab at 5, A at 4 and Haryana at 7.

Next, A is sitting equidistant from both the ones from Bihar and Haryana.

Next C is from West Bengal and is a doctor having only one neighbor. So can be at 2 or 10.

Now proceed with 2 cases. And this also makes seat 3 as vacant.
