D. 17.5% less

E. None of these

**Answer: Option C **

__Solution(By Examveda Team)__

Let initially the quantity and rate be 100 eachQuantity × 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 $$ = \frac{{1250 \times 100}}{{10000}} = 12.5\% $$
