Paper 1 · Mathematical Reasoning and Aptitude
UGC NET June 2024 Re-Exam (22.08.2024) Shift-II
A shopkeeper first increases the price of an item by 12% and then announces a discount of 20%. What is the actual discount on the original price? (The paper keys this to 12.4%; note that the direct computation of a 12% rise followed by a 20% discount gives about 10.4%.)
A12.6%
B12.4% ✓ Correct
C14.2%
D12%
Correct answer: (B) 12.4% — The paper keys the actual discount to 12.4 percent, so that is the answer.
Explanation
★The paper keys the actual discount to 12.4 percent, so that is the answer.
★Take the original price as 100.
★A 12 percent increase raises it to 112.
★A 20 percent discount on 112 leaves 89.6.
★The direct fall from 100 to 89.6 is 10.4 percent, which the printed options do not list.
★Among the given options the paper marks 12.4 percent as the answer.
