Seven persons A, B, C, D, E, F, and G are ranked according to their height. Who is/are taller than F?
Statement I: Height of B is more than
A. The number of persons taller than B is same as the number of persons shorter than
A. E is taller than G but shorter than
B. D is taller than F, who is shorter than
B. D is taller than
B. C is just shorter than F. E is not the fifth shortest person. Statement II: At most three persons are taller than
C. C is shorter than D and
B. E is just taller than
A. F taller than A but shorter than
B. F is neither the fourth shortest nor third shortest person. F is shorter than
D. M is not the shortest.

From statement I alone, Height of B is more than A. The number of persons taller than B is same as the number of persons shorter than A. E is taller than G but shorter than B. D is taller than F, who is shorter than B. D is taller than B. C is just shorter than F. E is not the fifth shortest person.

We get:

D(tallest) > B > F > C > E > A > G(shortest)


So, from statement I alone, we get D and B are taller than F.

So, data given in statement I alone is sufficient to answer the question.

From statement II alone, At most three persons are taller than C. C is shorter than D and B. E is just taller than A. F taller than A but shorter than B. F is neither the fourth shortest nor third shortest person. F is shorter than D. M is not the shortest. We get:

D/B(tallest) > B/D > F > C > E > A > G(shortest)

So, from statement II alone, we get D and B are taller than F.

So, data given in statement II alone is sufficient to answer the question.

Therefore, data given either in statement I alone or in statement II alone is sufficient to answer the question.
