उत्तर : 2. "decrease 12%"
व्याख्या :
Answer: B) decrease 12% Explanation: Given the price of a commodity is decreased by p = 20% And its consumption is increased by q = 10% Now, required increase or decrease in the expenditure on the commodity can be p + q + pq/100 = -20 + 10 - 200/100 = -10 - 2 = -12%. Hence, decrease in the expenditure = 12%
