    Solution

    Only X is heavier than R. X         R    _____   _____   _____   _____   _____ V is immediate heavier than W. W is not the lightest person. U’s weight is more than that of V’s weight. Average of W and U’s weight is equal to that of T’s weight. It means T must be lighter than U and heavier than F. X         R    U   T   V   W   _____ We get that S is the lightest person. X         R    U   T   V   W   S Weight of third heaviest person is 25kg and second lightest person is 15kg. X     R    U(25Kg)    T   V   W(15Kg)   S Average of W and U’s weight is equal to that of T’s weight. So, weight of T is: (25 + 15) / 2 = 40 / 2 = 20kg. Therefore, the final arrangement is X > R > U (25kg) > T (20kg) > V > W (15kg) > S
