A. 55 more

B. 10% more

C. 12.5% less

D. 17.5% less

E. None of these

Answer: Option C

Solution(By Examveda Team)

Let initially the quantity and rate be 100 each
Quantity × rate = Expenditure
100 × 100 = 10000
Now, Increase in price is 25% and new quantity is 70% of original
Quantity × rate = Expenditure
70 × 125 = 8750
Decreased expenditure,
= 10000 - 8750 = 1250
% decrease $$ = \frac{{1250 \times 100}}{{10000}} = 12.5\% $$

    125*70%=87.5
    So difference is 100-87.5=12.5
