      Solution

      Only R is heavier than L. P is immediate heavier than Q. Q is not the lightest person. O’s weight is more than that of P’s weight. Average of Q and O’s weight is equal to that of N’s weight. Weight of third heaviest person is 28kg and second lightest person is 16kg. R > L > O > N > P > Q > M We get Weight of O is 28kg and Weight of Q is 16kg. Weight of N is: (28 + 16) / 2 = 44 / 2 = 22kg. Therefore, the final arrangement is: R > L > O (28Kg) > N (22Kg) > P > Q (16Kg) > M
