UGC NET Questions (Paper – 1)

Statements A, B, C and E correctly summarise how pie charts work. A states that sector angles reflect relative shares. B is true because a full circle corresponds to 360 degrees. C is correct as pie charts emphasise contribution to a whole rather than precise comparisons between many categories. E is true since the total proportion is fixed at 100%, so increasing one share must reduce some other share. D is false because if the total quantity is known, one can estimate or compute numeric values from the percentages shown. Hence A, B, C and E only are correct.

Option A:
Option A is correct because it includes all the valid properties of pie charts and excludes D, which overstates the limitation of estimating values from them.

Option B:
Option B is incomplete as it omits E and thus fails to stress the compensating changes between categories when one sector grows, which is central to understanding proportions.

Option C:
Option C is wrong because it leaves out A and therefore misses the fundamental encoding rule (angles proportional to shares).

Option D:
Option D is incorrect because it omits B and does not include all the true statements together, so it cannot be correct.

Statements A and B are correct descriptions of bar graphs and pie charts, and D is true because meaningful comparison of graphical data demands careful reading of scales, units and legends. Statement E is also correct since many exam questions allow or even require approximations for quick decision-making. Statement C is false because ignoring scales can lead to serious misinterpretation of data. Thus, the combination that includes A, B, D and E while excluding C is correct.

Option A:
Option A is incomplete because although it lists three true statements, it omits E and does not highlight the practical exam strategy of using approximations where appropriate. This reduces the applied insight necessary for UGC NET aptitude.

Option B:
Option B is insufficient since it leaves out A, failing to acknowledge the fundamental principle that bar lengths are proportional to values, which is basic to understanding bar graphs. Without A, the description of graphical interpretation is partial.

Option C:
Option C is incorrect because it includes C, the statement that minimises the importance of scales, and therefore accepts a guideline that would lead to faulty interpretation. Even though A, B and D are true, adding C makes the combination unsound.

Option D:
Option D is correct because it keeps the four accurate statements and rejects C, which directly contradicts best practice in reading graphs. It aligns with the skills expected in data interpretation sections of UGC NET.
