Answer A.
Table 1: Price and quantity demanded of Cheese
Quantity of price Quantity of cheese Estimated quantity of
cheese
$1.00 800 gm. 1 kg
$1.20 700 gm. 900 gm.
$1.40 600 gm. 800 gm.
$1.60 500 gm. 700 gm.
$1.80 400 gm. 600 gm.
From the above table it can be observed that with the rise in the price level of cheese, the
quantity purchased by the consumers would be decreased. As per the law of demand, price
level of the product and the quantity demand is adversely related to each other. Now, if my
income level will be increased by 50%, then my capacity of purchasing product will be also
increased.
Answer B.
Quantity of price Quantity of cheese Number of consumers
$1.00 800 gm. 600
$1.20 700 gm. 550
$1.40 600 gm. 500
$1.60 500 gm. 450
$1.80 400 gm. 400
The economy of the kingdom of Saudi Arabia is highly developed and therefore, it can be
said that the customers will be able to purchase the product even after raising the price level.
Therefore, the decreasing of demand for the product is less after rising the price level. Hence,
the individual demand curve is steeper than the market demand curve. However, if the
aggregate income level would be increased by 50%, then the demand would not be increased
much than the individual demand (since, the supply is constant).
