UGC NET Questions (Paper – 1)

Statements A, B, C and D summarise key facts for calendar questions. A correctly notes that 365 days leave 1 odd day beyond 52 weeks. B is true for leap years with 366 days and 2 odd days. C is correct because adding multiples of 7 days cycles the week back to the same weekday. D correctly defines odd days as leftovers after full weeks are removed. E is false since adding 7 days returns to the same weekday, not the next one. Therefore, A, B, C and D only are correct.

Option A:
Option A is incomplete as it omits D and thus fails to define odd days explicitly, even though that concept is central to computing weekday shifts.

Option B:
Option B is incomplete because it omits B and/or C and does not capture the full set of rules needed for weekday calculations.

Option C:
Option C is correct because it combines facts about year lengths, odd days and the effect of multiples of seven on weekdays, while excluding E, which misstates how adding 7 days affects the day of the week.

Option D:
Option D is wrong since it includes E (false) and omits A (true), so it both adds an error and loses a key fact.

Statements A and B are true because the weekday sequence repeats every seven days and a non-leap year of 365 days shifts the starting weekday by one day in the next year. Statement E is also correct since many calendar questions ask candidates to determine the weekday for a given date. Statement C is false because leap years have 366 days, and D is false because century years must be divisible by 400, not merely by 4, to be leap years. Hence, the combination A, B and E only is correct.

Option A:
Option A is incomplete as it omits E and does not explicitly connect the calendar structure to typical exam tasks that require finding weekdays. Without E, the applied dimension of the topic is missing.

Option B:
Option B is correct because it groups the three true statements about the cyclic nature, year shift and exam usage of calendar facts, while rejecting C and D, which misrepresent leap-year and day-count rules. It thus matches the logical content of NET-level calendar questions.

Option C:
Option C is wrong because it adds C, which incorrectly assigns 365 days to leap years, and still omits D, failing to discuss the additional condition for century years. Including C makes the option factually incorrect.

Option D:
Option D is incorrect since it includes D, the statement that ignores the special rule for centuries, and therefore endorses a mistaken description of the Gregorian calendar. This misclassification invalidates the option.

Statements A and B correctly describe the length of non-leap and leap years and the divisibility rule used to identify leap years. Statement C is true because the weekly cycle repeats every 7 days, and E is also correct as calendar questions usually count odd days from a known reference day. Statement D is false because odd days are calculated modulo 7, not modulo 5. Therefore, the combination A, B, C and E only is correct.

Option A:
Option A is incomplete because it omits E and therefore misses the practical step of accumulating odd days from a reference, which is crucial for solving day-of-week problems. Without E, the method is not fully described.

Option B:
Option B is wrong as it includes D, which uses modulo 5 instead of modulo 7, and so miscalculates odd days. This incorrect rule makes the entire option unacceptable.

Option C:
Option C is incomplete since it leaves out A and B, thereby not explicitly stating the year-length facts and leap-year rule, even though it contains two true statements.

Option D:
Option D is correct because it gathers all the true statements and excludes D, the incorrect modulus rule, giving a complete and accurate picture of odd-day calculations in calendar questions.
