Practice questions on Data Sufficiency - Ranking and Order — with answers

Try each question first, then open the answer. Explanations are included.

1. What is Aman's rank from the top in the class? Statement I: Aman scored more than at least 15 students in the class. Statement II: The total number of students in the class is 35.

  1. AStatement I alone is sufficient to answer the question, while Statement II alone is not sufficient
  2. BStatement II alone is sufficient to answer the question, while Statement I alone is not sufficient
  3. CBoth statements together are sufficient to answer the question, but neither statement alone is sufficient
  4. DBoth statements together are not sufficient to answer the question
Show answer

Answer: D

Statement I alone only gives a lower bound (at least 15 students scored less than Aman), not the exact number, so the exact rank cannot be found. Statement II alone only gives the total class size, with no information about Aman's relative performance. Even combining both, since Statement I gives only an inequality rather than an exact count, Aman's exact rank from the top still cannot be uniquely determined. Hence both statements together are not sufficient.

2. What is Aman's rank from the top in the class? Statement I: Aman scored more than at least 21 students in the class. Statement II: The total number of students in the class is 29.
