Ordering and ranking problems – UGC NET Question

Statements A and B correctly describe the basis of ranking problems and the technique of using top and bottom positions to deduce total count, while D notes that composite ranking across subjects or criteria is sometimes required. Statement C is false because if someone is 5th from the top and 10th from the bottom, the total is 5 + 10 − 1 = 14, not 10. Statement E is also false since such questions do appear under mathematical reasoning and aptitude. Therefore, the combination A, B and D only is correct.

Option A:
Option A is incomplete as it omits D and therefore does not discuss the more advanced type of problems that combine rankings from different subjects or tests. Without D, the picture of ranking questions is less comprehensive.

Option B:
Option B is correct because it includes all the true statements and excludes C and E, both of which give wrong information about totals and syllabus coverage. It matches the patterns seen in NET-level ordering and ranking problems.

Option C:
Option C is wrong since it includes C, which miscomputes the total, and omits A, failing to mention the basic nature of ranking criteria such as marks or height. This mixture renders the option unsuitable.

Option D:
Option D is incorrect because it contains C and thus accepts an incorrect total, even though it includes some true statements. The presence of C makes the overall combination invalid.
