Who sits diagonally opposite to the one who likes Chennai?

By using given information, B sits at the corner and likes Mumbai. Only two persons sit between B and the one who was born in an odd numbered date which is greater than 24 (25 or 27). There are two possible cases. (ii)- D sits third to the right of G and was born on 22nd. D is not an immediate neighbour of B. D face inside the centre and not an immediate neighbour of F and only two persons sit between F, who likes Hyderabad and E, who face inside the centre. In case-1: G sits immediate left of B and F sits immediate right of B. In case-2: G sits third to the left of B and F sits immediate left of B. C faces inside the centre. There is only one position left for C. A sits second to the left of H who likes Bhopal. Hence position of all persons is fixed in both cases. (iii)- B was born on the date which is an odd number. The one who was born on 23 like Dehradun and faces centre. There is only possibility B was born in 21 because he likes Mumbai. The one who like Kochi sits second to the right of the one who likes Chennai. Neither C nor A likes Chennai. G neither likes Chennai nor yellow. Hence D likes black, E likes Kochi and C likes Dehradun. The youngest person likes Mumbai and A is not the oldest person. Hence case-2 will be eliminated and in case-1: G likes Mumbai and born on 28 and A likes Bangalore and born on 25 because the one who likes Bangalore was born on 25. E is 2 days older than F. Hence E was born on 24 and F was born on 26.
