UGC NET Questions (Paper – 1)

Statements A, B and C capture the standard relationships between percentages and angles in a pie chart. A correctly states that the entire circle is 100 percent. B gives the direct formula for converting a percentage to its central angle. C provides the inverse operation, dividing the angle by 3.6 to obtain the percentage. D is false because if the total value is given, absolute amounts for each sector can be calculated from percentages, and E is false since bar graphs are usually better for exact comparisons when many categories have similar sizes. Therefore, A, B and C only form the correct set.

Option A:
Option A is correct because it includes all three true statements about percentage–angle conversions and excludes D and E, which misrepresent the capabilities and comparative usefulness of pie charts. It gives exactly the relationships that candidates routinely use in NET data interpretation.

Option B:
Option B is incomplete, as it covers only A and B and ignores C, thereby failing to mention the reverse conversion from angles back to percentages. Without C, the explanation of how to read pie charts is only half finished.

Option C:
Option C is incorrect because it includes D, the false claim that absolute totals can never be deduced when totals are known, and thus mixes an error into an otherwise correct combination. Once a wrong statement is included, the option cannot be considered correct.

Option D:
Option D is wrong because it omits A and adds only B and C, not explicitly affirming that the full circle represents 100 percent, and also does not address the incorrect statements in D and E. This makes it an incomplete and therefore invalid combination.
