Elasticity of Demand & Supply Class 12th Physics Important Objective Question 2024

Results

#1. In market economies, most production and consumption decisions are guided by

government decree

foreign countries (imports and exports)

monopolists’ desires to maximize profits

individual choice under the price system

#2. In general, “elasticity” can measure

whether a price increase causes quantity

the strength of an economy’s tendency to recover from recession

the responsiveness of decision makers to economic changes in prices

#3. 3. More “elastic” means

a. less desirable

b. less desirable

c. less responsive

d. more responsive

For example, in a perfectly competitive market, if a firm (let’s say a farmer) charges a price higher than the market price its sales will drop to zero. Why would anyone buy from a higher priced firm if they can buy exactly the same thing from a multitude of other firms? In this case the responsiveness is absolute, the demand curve is perfectly elastic.

#4. 4. Price elasticity of demand is calculated as

a. the percentage change in quantity demanded divided by the percentage change in price

b. the percentage change in price divided by the percentage change in quantity demanded

c. the absolute change in quantity demanded divided by the absolute change in price

a. price and demand are directly related

b. price and demand are inversely related

c. price and quantity demanded are inversely related

#6. 6. In calculating price elasticity of demand, we use average price and average quantity as our base value because

a. it reduces the complexity of the formula and makes the calculation easier

#7. 7. Price elasticity of demand is not influenced by

a. the number of substitutes available

b. the proportion of the consumer’s budget spent on the good

c. the length of the time period under consideration
