Q1 :

Give equation of Budget Line.


Answer :

The equation for budget line is as follows.
P1X1+ P2X2 = M
 Where,
P1 represents price of good 1
 P2represents price of good 2
M represents income of the consumer
 

Q2 :

When income of the consumer falls the impact on price-demand curve of an inferior good is : (choose the correct alternative)
(a) Shifts to the right.
(b) Shifts of the left.
(c) There is upward movement along the curve.
(d) There is downward movement along the curve.


Answer :

Demand for inferior goods share a negative relationship with consumer's income. So, when the income of the consumer falls, the demand for an inferior good increases leading to the rightward shift of the demand curve.
Hence, the correct answer is option (a).

Q3 :

If Marginal Rate of Substitution is constant throughout, the Indifference curve will be : (choose the correct alternative)
(a) Parallel to the x-axis.
(b) Downward sloping concave.
(c) Downward sloping convex.
(d) Downward sloping straight line.


Answer :

If Marginal Rate of Substitution is constant throughout, the Indifference curve will be downward sloping straight line.
Hence, the correct answer is option (d).

Q4 :
