Six persons A, B, C, D, T and U have different marks in a class test. Who has 2nd highest marks? Statement I: C has more marks than D and T. At least two persons have more marks than
C. A has 3rd lowest marks. B doesn’t have the highest marks. D doesn’t have the lowest marks. Statement II: Three persons have lesser marks than
C. Neither B nor U has fewer marks than
C. A has more marks than D and T.

From statement I alone, as C has more marks than D and T. At least two persons have more marks than C. A has 3rd lowest marks. B doesn’t have the highest marks. D doesn’t have the lowest marks, so U  >  B  >  C > A > D > T Clearly, B has 2nd highest marks. From statement II alone, as three persons have lesser marks than C. Neither B nor U has less marks than C. A has more marks than D and T, so U / B  >  B / U >  C > A > D / T > T / D Either B or U has 2nd highest marks. Data given in statement I alone is sufficient to answer the question.
