1.  Questions : Among P, Q, R, S and T, Q is the second tallest and S is immediate taller than the shortest . Who among them is in the middle when they stand in the order  of their heights.
Statements :

I.   T is not the shortest.
II.  R is taller than S but shortest than Q.
III. P ranks third in height above S when all are arranged in the order of height.

A. Only I and II
B. Either II only or I and III only
C. Only II
D. Only II and III
E. None of these

Answer: Option B

Explanation:

From the given statement, the descending order of heights is : _, Q, _, S, _.

From II, we have the order : _, Q, R, S, _. Thus, R is in the middle.

From III, we have the order : P, Q, _, S, _. But, according to I, T is not the shortest.

So, R is the shortest. Thus, we have the order : P, Q, T, S, R. So, T is in the middle.
