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,
= (1250*100)/10000
= 12.5%.

SO , Option (C) is the right answer ✔️
