Data sufficiency in aptitude tests – UGC NET Question

Statements A and B describe the core task and one possible sufficiency pattern, D highlights that sometimes both statements together are needed and E correctly notes that these questions focus on judging sufficiency rather than performing detailed computation. Statement C is false because in many data sufficiency items it is enough to determine that a unique answer can be found in principle, without actually computing it. Therefore, the combination A, B, D and E only is correct.

Option A:
Option A is incomplete because it omits E and so underplays the fact that data sufficiency emphasises reasoning about information rather than heavy calculation. Without E, the skill focus of these questions is not fully captured.

Option B:
Option B is also incomplete since it leaves out A, failing to mention explicitly that the central goal is to determine sufficiency of information, not to solve the problem numerically. This omission weakens the conceptual framing.

Option C:
Option C is wrong because it includes C, the mistaken requirement to always compute exact answers, and it also omits E, thereby misrepresenting the very philosophy of data sufficiency questions.

Option D:
Option D is correct because it contains all the true statements about how sufficiency is judged and how statements are used, while excluding C, which contradicts standard instructions for such items. It aligns with UGC NET-style data sufficiency patterns.
