The price of a certain food items was raised by 12% in market. The consumption of the same food items was decreased from 250 kgs to 200 kgs. By how much percent will expenditure on food item fall in the market? Correct Answer 10.4%

Let initial price of food be Rs. 100

As known,

Expenditure = price × consumption

For price 100 consumption is 250 kgs

Expenditure = 100 × 250 = 25000.

Price of a food items is increased by 12%.

New price of food item = 100 + 100 × 12/100 = 112

New expenditure = 112 × 200 = 22400.

Change in expenditure 

= × 100
