UGC NET Questions (Paper – 1)

A, B and C describe good principles of reading a single graph: scale affects visual impression, legends identify categories and, within one graph, equal heights match equal values. D is wrong because equal heights on different graphs with different scales may correspond to different actual values. E is also wrong because in many data interpretation questions candidates must convert units (such as thousands to lakhs or minutes to hours). Therefore, D and E only are the incorrect statements.

Option A:
Option A captures only D as wrong and overlooks E, which incorrectly claims unit conversions are never needed. Because it fails to include all wrong statements, this option is not adequate.

Option B:
Option B treats only E as wrong and ignores the error in D regarding comparing heights across graphs with different scales. Thus it also fails to identify the complete set of wrong statements.

Option C:
Option C is correct because it selects both D and E, the two statements that mislead about cross-graph comparisons and the need for unit conversions, while leaving A, B and C intact as good interpretation practices.

Option D:
Option D incorrectly adds C to the set of wrong statements even though C is true for any single graph using a consistent scale. Including C makes this combination inaccurate.

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.
