Direction: Study the following information carefully and answer the questions given below:

Seven persons M, N, O, P, Q, R, and S have different heights and weights. A person according to his/her weight and height is to be selected from the group. A list was prepared in which the height and weight of these seven students were written in decreasing order in two separate vertical columns.

A @ B means A is not taller than B.

A % B means A is not heavier than B.

O % N % S, M @ N, O % P, M % N

Further, it is known that only one person has the same position in the weight and height column. An equal number of persons are taller and shorter than Q. M is heavier than two persons. O is taller than only S. N is shorter than at least two persons. P is not the heaviest. S is lighter than two people. R is the second heaviest person.
