The question given below consists of two statements numbered I and II below them. You have to decide whether the data provided in the statements are sufficient to answer the question. Read all the statements and give answer:
Five persons A, B, C, D and E have different heights. Who among the following is third tallest?
Statement I: D is taller than A and shorter than B. B is shorter than C.
Statement II: C is not the tallest but taller than D.
From statement I alone, only the order of B, D, C, A can be determined (C > B > D > A, in descending order of their height) From statement II alone, only C is not the tallest can be determined. Using both statement I and II, E is tallest and thus, B is the third tallest person. So, the order is E > C > B > D > A. The data given in both statements I and II together is sufficient to answer the question.
