• D. If the data in both statements I and II together are necessary to answer the question

Answer 1

The correct option is B

If the data either in statement I alone or in statement II alone are sufficient to answer the question

From I, we know that in a class of 25 student's, A ranks 18${}^{th}$ from the bottom and 16${}^{th}$ from the top. Sachin is 3 ranks above A and so, S ranks 13${}^{th}$ from the top. From II, D ranks 24${}^{th}$ from the bottom and hence, 2${}^{nd}$ from the top. S, being 2 ranks below D, is, thus, 4${}^{th}$ from the top.
