Six persons R, S, T, U, V and W have different heights. Who is the second tallest person? Statement I: R is taller than V and U. S is taller than T but shorter than W. R is shorter than S. Statement II: T is shorter than only two persons. S is taller than R but not the tallest. V is taller than only U.

From statement I, R is taller than V and U. S is taller than T but shorter than W. R is shorter than S. We get: W (tallest) > S > T/R > R/T > V/U/T > T/U/V (shortest) From statement I alone, we get S is the second tallest person. From statement II, T is shorter than only two persons. S is taller than R but not the tallest. V is taller than only U. We get: W (tallest) > S > T > R > V > U (shortest) From statement II alone, we get S is the second tallest person. Therefore, data given in either statement I or II alone is sufficient to answer the question.
