51. 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 shorter 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
Explanation
- A
1 is not enough
2 ‘We are friends’ should have only ‘We’ common with another statement, so enough to get value.
52. Four subjects – Physics, Chemistry, Mathematics and Biology – were taught in four consecutive periods of one hour each starting from 8.00 a.m. At what time was the Chemistry period scheduled ?
Statements:
I. Mathematics period ended at 10.00 a.m., which was preceded by Biology.
II. Physics was scheduled in the last period.
III. Mathematics period was immediately followed by Chemistry.
A. Only I
B. Either I only or II only
C. Only II
D. Only II and III
E. Only I and either II or III
Explanation
E From I and II, we conclude that Mathematics period began at 9.00 a.m., Biology period began at 8.00 a.m. and Physics period began at 11 a.m. So, the Chemistry period began at 10.00 a.m. From I and III, we conclude that Mathematics period ended and Chemistry period began at 10.00 a.m.

54. Who is the tallest among six boys P, T, N, D, Q and R ?
Statements:
1. P is taller than D and N but not-as tall as T.
2. R is taller than Q but not as tall as T.
A. Only 2 follows
B. Both follows
C. None follows
D. Only 1 follows
E. Either A or B follows
Explanation
- B From I, we have: P > D, P > N, T > P i.e. T > P > D > N or T > P > N > D …(i)
From II, we have: R > Q, T > R i.e. T > R > Q …(ii)
Clearly, from (i) and (ii), we conclude that T is taller than each one of P, N, D, R and Q. So, T is the tallest.
