Answer: (b)

If R is a representative, L cannot be a representative. Also, M is not a representative. So, K and N are the representatives from faculty members.

From (iii), since M is not a representative, so P cannot be a representative from students.

Thus, either Q or S is the second representative from students.

Answer: (a)

If neither Q nor S is a representative, P and R are representatives from students. If R is a representative L cannot be a representative.

Thus, K is one of the representatives from faculty members as either K or L must be one of the representatives. If P is a representative, M must also be a representative.

Hence, K and M is the pair of faculty members who must be representatives.

Answer: (b)

From (ii), if L is a representative, K cannot be a representative.

Hence, (d) is incorrect.

From (iv), if L is a representative, R cannot be a representative. So, (c) is ruled out.

From (iii), if P is a representative, M must also be a representative. So, (a) is also wrong.

Hence, only (b) holds.
