A consumer of a single commodity is in equilibrium when
He can equate his demand with price
He equates marginal utility and price
He can equate his marginal and total utilities
His marginal utility is equal to zero
Correct answer is B
A consumer is in equilibrium when the marginal utility equal to the price of the commodity i.e MUx = Px.
Where : X = the commodity
MU = Marginal utility
P = price of the commodity
Therefore, a consumer who consume a single commodity such as apple will be at equilibrium when MUa = Pa

What is the ratio of expenditure on health to Agriculture if the yearly budget is 7200?
2:3
3:4
4:3
5:4
Correct answer is B
Health = 60/360 x 7200
= 1200
Agriculture = 80/360 x 7200
= 1600
The ratio of expenditure on health to agriculture = 1200/1600
= 3:4
In perfectly elastic supply, the supply curve
Is vertical
Is horizontal
Slopes upward
Slopes downward
Correct answer is B
A perfect elastic supply curve is the one in which the supply curve is perfectly horizontal. It is a theoretical curve and such a curve does not actually exist in practice.
The supply curve of a locally-produced good may shift to the right if
There is an increase in taxes on inputs
Government increases subsidies
Rural-urban migration is encouraged
The price of the commodity increases
Correct answer is D
One of the law of supply is, as price increases , the quantity demanded also increase due to the positive relationship. Therefore, an increase in price will shift the supply curve to the right.

Correct answer is C
e = ∆Qd/∆P x P/Qd
= 30 - 20/ 5 - 4 x 4/ 20
= 10/1 x 4/20
