Data interpretation percentage change – UGC NET Question

Statement A correctly gives the standard formula for percentage change. Statement B is also true because a negative result indicates that the new value is lower than the old one. Statement E is correct as many data interpretation graphs require reading approximate values and working with reasonable approximations. Statement C is false because changing the base (denominator) alters the percentage value, and D is false since a large absolute difference can still yield a small percentage change when the base is large. Thus, A, B and E only are correct.

Option A:
Option A is incomplete because it leaves out B, which properly explains the meaning of a negative percentage change.

Option B:
Option B is correct as it combines the correct formula, the interpretation of negative change and the realistic note about approximation, while excluding C and D.

Option C:
Option C is wrong because it includes C, which wrongly claims the base value does not matter, and it omits B.

Option D:
Option D is incorrect since it contains D (false) and omits A (formula).
