UGC NET Questions (Paper – 1)

Statements A, B, C and E give standard reasoning techniques for ranking questions. A states the usual formula for total persons when one person’s ranks from top and bottom are known with no ties. B is true because ties disturb this simple formula. C is correct; it uses transitivity of “taller than” to deduce the relation between A and C. E is also correct since drawing a vertical list helps many candidates see the order clearly. D is false because equal scores can lead to shared ranks, so requiring distinct ranks is not correct. Thus, A, B, C and E only form the correct set.

Option A:
Option A is incomplete because it leaves out E, failing to mention the practical diagrammatic strategy that aids in solving ranking questions, even though A, B and C are true.

Option B:
Option B is also incomplete, as it includes only B, C and E and omits A, losing the widely used formula for computing total persons.

Option C:
Option C is correct since it brings together the numerical formula, the effect of ties, transitivity of order and the usefulness of diagrams, while excluding D, which incorrectly denies the possibility of equal ranks.

Option D:
Option D is wrong because it features D, which misstates the treatment of equal scores, and omits B, so it both includes an error and loses a critical observation about ties.
