UGC NET Questions (Paper – 1)

Statement B is the only wrong statement in this group. A is correct because data sufficiency focuses on whether information is enough, not on computing the final number. C is true since some questions are solvable with one statement but not with the other alone. D is also correct because in some cases, even combining statements fails to give a unique answer. E is correct since we generally presume the given data are consistent unless told otherwise. B is false because two insufficient statements may remain insufficient when combined.

Option A:
Option A is incorrect as it treats both A and B as wrong, even though A accurately states the objective in data sufficiency problems. Misclassifying A makes the option invalid.

Option B:
Option B is correct because it isolates B as the sole incorrect statement, capturing the fact that insufficiency of each statement alone does not guarantee sufficiency when combined.

Option C:
Option C is wrong because it wrongly marks C as wrong as well, even though C describes a common situation where one statement alone can be sufficient.

Option D:
Option D is incorrect since it ignores B altogether and claims only C and D are wrong, even though D and C correctly describe typical sufficiency patterns and B is the problematic rule.
