UGC NET Questions (Paper – 1)

Statements A, B and C correctly give the basic angular speeds for clock hands: 360 degrees per full rotation, 6 degrees per minute for the minute hand and 0.5 degrees per minute for the hour hand. Statement E is also true because many questions involve finding when the hands coincide or form a given angle by using relative speed. Statement D is false since at 3:00 the angle between the hands is 90 degrees, not 60. Thus A, B, C and E together form the correct set.

Option A:
Option A is incomplete as it omits E and therefore does not mention the key technique of using relative speed, which is central for higher-level clock questions in NET. This makes the option only partially accurate.

Option B:
Option B is incomplete because it omits B (minute hand speed), so it does not include all true statements even though A, C and E are correct.

Option C:
Option C is correct because it includes all true statements and excludes D, which misstates the 3:00 angle. It represents the full conceptual toolkit for handling typical clock-angle questions.

Option D:
Option D is incorrect since it includes D, the wrong value for the angle at 3:00, and it omits A, ignoring the basic 360-degree fact. This mixture of an error with an omission makes the option invalid.
