Question : If the price of apples increases from Rs. 80 per kg to Rs. 100 per kg, by what percentage should the consumption of apples decrease so that the expenditure remains the same?
Option 1: 25%
Option 2: 22%
Option 3: 20%
Option 4: 18%
Correct Answer: 20%
Solution : Here the expenditure is the same. So, price will be inversely proportional to consumption. Price increases from 80 to 100. therefore, the quantity decreases from 100 to 80. Reduction in the quantity $=\frac{100 – 80}{100}\times 100=\frac{20}{100}\times 100 = 20$% Hence, the correct answer is 20%.
