What is S's rank from the top in a class of 25 students ?
Statement I. S ranks three ranks above A who ranks 10th from the bottom.
Statement II. S's rank from the top is two ranks below D who ranks 24thfrom the bottom.
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 18th from the bottom and 16th from the top. Sachin is 3 ranks above A and so, S ranks 13th from the top. From II, D ranks 24th from the bottom and hence, 2nd from the top. S, being 2 ranks below D, is, thus, 4th from the top.
