Answers:

Direction (1-5)

 

H is 2^nd from one of the ends. E is 70kg and two persons are sitting between E and H.

Case 1:

	H			E
				70

 

Case 2:

			E			H
			70

 

Take case 1:

B is 2^nd to the left of A. B is not neighbor of H. A and B are not sitting at any end.

	H		B	E	A
				70

Only one person is lighter to B so B is 60kg. H is lighter to E but heavier to B so H is either 63 or 66kg. D is lighter to H and neighbor of A. The one whose weight is 63kg is 2^nd to the left of F. F is not neighbor of B. From this A is 63kg but it is given A is not 63kg so this case gets rejected.

	H		B	E	A	D	F
			60	70	63

 

Take Case 2:

B is 2^nd to the left of A. B is not neighbor of H. A and B are not sitting at any end. Only one person is lighter to B so B is 60kg.

		B	E	A		H
		60	70

 

The one whose weight is 63kg is 2^nd to the left of F. F is not neighbor of B. D is lighter to H and neighbor of A so D is 63kg.

		B	E	A	D	H	F
		60	70		63

 

The number of persons are heavier to F is same as lighter to D so F is 74kg. H is lighter to E but heavier to B so H is 66kg. A is lighter to E so A is 56kg. Two persons are sitting between the one whose weight is 80kg and the one whose weight is 56kg.

		B	E	A	D	H	F
85	80	60	70	56	63	66	74

G is not the heaviest person. So C is 85kg and G is 80kg.

 

Here is the final arrangement:

C	G	B	E	A	D	H	F
85	80	60	70	56	63	66	74
