(Q. 1) The price elasticity of demand is the ratio of thea. absolute change in quantity demanded to the absolute change in price.b. absolute change in price to the absolute change in quantity demanded.c. percentage change in price to the percentage change in quantity demanded.d. percentage change in quantity demanded to the percentage change in price. 2.

(Q. 4) Utility is an artificial construct used as a means of measuring thea. price of a good.b. costs of producing a good.c. difference between the price and the value of a good.d. satisfaction one receives from the consumption of a good. 9. (Q. 5) The law of diminishing marginal utility can be stated as follows:a. As the amount of a good consumed increases, the sum of satisfaction received tends to decrease.b. As the amount of a good consumed increases, the additional satisfaction gained from consuming additional units tends to decrease.c. As the amount of a good consumed decreases, the additional satisfaction gained from consuming additional units tends to increase.d. As the amount of a good consumed increases, the sum of satisfaction received tends to increase but at a diminishing rate.e. b and d Exhibit 1Number ofPlums Total Utilityof Plums1 202 363 504 625 72 10. (Q. 5) Refer to Exhibit 1. The marginal utility of the second plum isa. 20b. 18c. 16d. 14e. 10 11. (Q. 6) Suppose for a consumer the marginal utility (MU) of bread is 10 utils and the MU of milk is 20 utils, the price of bread is $1 and the price of milk is $1. Given this,a. more utility per dollar is gained from consuming milk than bread.b. more utility per dollar is gained from consuming bread than milk.c. the same amount of utility per dollar is gained from consuming milk as bread.d. the consumer is in consumer equilibrium. 12. (Q. 6) If a person is receiving greater utility per dollar from consuming one good than another, it follows that he or she isa. maximizing disutility.b. not maximizing utility.c. maximizing utility.d. There is not enough information to answer the question. 13. (Q. 6) Suppose a consumer is purchasing Coke (c) and pretzels (p) in quantities such that he is achieving consumer equilibrium. Then the price of Coke increases. Which of the following will be true?a. MUC/PC = MUP/PPb. MUC/PC > MUP/PPc. MUC/PC < MUP/PPd. We cannot say for certain what will happen to the MUC/PC relative to the MUP/PP. 14.

Water, a necessity, has a relatively low price whereas diamonds, usually a luxury, have a relatively high price.b. Although water appears to have a relatively low price when compared to diamonds, in reality, it has a relatively higher price.c. Although water appears to have a relatively low price when compared to diamonds, in reality, the prices are equal.d. Although water appears to have a relatively low price when compared to diamonds, at the margin, water has the relatively higher price.e. Although water appears to have a relatively low price when compared to diamonds, at the margin, the prices are equal. 16.
