Discussion

A question is given, followed by two statements labelled I and II. Read the question and the statements, and decide whether the data provided in the statements are sufficient/necessary to answer the question.

Question:
Who is the tallest among A, B, C, D and E?

Statements:
I. B is taller than only D. E is taller than A and C.
II. D is shorter than B. A is shorter than only E.

  • A.The data in Statement I alone are sufficient to answer the question, while the data in Statement II alone are not sufficient to answer the question.
  • B.The data in Statement II alone are sufficient to answer the question, while the data in Statement I alone are not sufficient to answer the question.
  • C.The data given in both statements I and II together are necessary to answer the question.
  • D.The data either in statement I alone or in statement II alone are sufficient to answer the question.

Answer: D

Either statement alone is enough, and in both E is the tallest. Statement I: B is taller than only D, so exactly one person is shorter than B, and A, C and E are all taller than B. E is taller than A and C, so the order is E, then A and C, then B, then D, with E tallest. Statement II: A is shorter than only E, so only E is taller than A. D is shorter than B and A is above B, C and D, so E is again the tallest.

Options 1 and 2 each say that one statement is insufficient, which is false, and option 3 says both are needed, which is also false.
