In a two good world there is an individual with income m = 3 and utility function is given by u = = x^0.5y^0.5 . The price of good x is Re. 1 per unit and the price of good y is also Re. 1 per unit.

If the individual can consume any non negative amount of good x and y, then the optimum consumption bundle is

x = 1, y = 1

x = 1.5, y = 1.5

x = 2.5, y = 0.5

x = 0, y = 3

2 / 11

In a two good world there is an individual with income m = 3 and utility function is given by u = x^0.5y^0.5. The price of good x is Re. 1 per unit and the price of good y is also Re. 1 per unit.

If the individual can consume either zero unit of good x or at most one unit of x and any non-negative amount of good y, then the optimum consumption bundle is

x = 1, y = 2

x = 1, y = 3

x = 0, y = 3

x = 3, y = 3

3 / 11

In a two good world there is an individual with income m = 3 and utility function is given by u = x^0.5y^0.5. The price of good x is Re. 1 per unit and the price of good y is also Re. 1 per unit.

If both goods x and y can be consumed in integer amounts (i.e., zero unit, one unit, two units etc.) then the optimum consumption bundle is

x = 3, y = 1

x = 1, y = 3

x = 3, y = 0

x = 1, y = 2 or x = 2, y = 1

4 / 11

Suppose a consumers preferences over commodities 1 and 2 can be represented by the utility function U(x₁, x₂ ) = min⁡{ x₁, x₂ } + max{ x₁, x₂ }, where x₁, x₂ ≥0. The prices of the two commodities are 1 and 2 respectively and the consumers income is 150. Which of the following is true?

At the optimum, the consumer should consume 150 units of commodity 1 and none of commodity 2.

At the optimum, the consumer should consume 75 units of commodity 2 and none of commodity 1.

At the optimum, the consumer should consume 50 units of commodity 1 and 50 units of commodity 2.

At the optimum, the consumer should spend equal amount on the two commodities.

5 / 11

There are three commodities - the first commodity has a negative price -1 per unit, the second commodity is priced at +1 per unit and third is priced at +2 per unit. Income of the person is 100 per day. Then which one of the following is not true?

An individual may afford to consume the positive amounts of each per day

An individual may afford to consume any amounts of goods 2 and 3 per day

An individual may afford to consume (0, 0, 60)

An individual may afford to consume (20, 0, 60)

6 / 11

Satish is very conscious about the food he eats. He only eats rotis and dal; a cup of dal costs Rs. 2 while each roti costs Re. 1 and Satish decides to spend Rs. 13 per day on food. Also he decides to consume exactly 5500 calories a day; he has been told that each roti has 1000 calories while each cup of dal has 500 calories. He spends his entire money allotted on foods. Then

He consumes 3 rotis and 5 cups of dal.

He consumes no more than 3 rotis per day.

He consumes no more than 5 cups of dal per day.

Unless we are given some more information about preference, we cannot say what Satish does.

Let the following utility function represent the preference relation of an individual

U(x, y) = x^0.5 + y
Let Px, Py and M denote the prices of good x, y and money income respectively. Px, Py, M > 0

Optimal consumption bundle of the consumer includes

Only good x

Only good y

both goods x and y

cannot say

8 / 11

Let the following utility function represent the preference relation of an individual

U(x, y) = x^0.5 + y
Let Px, Py and M denote the prices of good x, y and money income respectively. Px, Py, M > 0

Given prices, as M increases optimal consumption of x

increases

9 / 11

Let the following utility function represent the preference relation of an individual

U(x, y) = x^0.5 + y
Let Px, Py and M denote the prices of good x, y and money income respectively. Px, Py, M > 0

Let Py = 2, Px = 1/4m, optimal consumption bundle includes

Only good x

Only good y

both goods x and y

cannot say

10 / 11

Let the following utility function represent the preference relation of an individual

U(x, y) = x^0.5 + y
Let Px, Py and M denote the prices of good x, y and money income respectively. Px, Py, M > 0

If Px = Py in the optimal consumption bundle

equal amount of x and y is consumed

consumption of x is more than y

consumption of y is more than x

cannot say

11 / 11
