Chapter 4: Costs and Revenue (Set-3)

Total revenue (TR) is calculated as

A Price × Quantity sold
B Total cost ÷ Output
C Marginal cost × Output
D Profit + Total cost

Average revenue (AR) is

A TR – TC
B TR ÷ Quantity sold
C TC ÷ Quantity produced
D MR ÷ Quantity

Marginal revenue (MR) refers to

A Revenue per unit sold
B Total revenue at equilibrium
C Additional revenue from selling one more unit
D Difference between TR and profit

If a firm sells 10 units at ₹20 each, its TR is

A ₹200
B ₹30
C ₹2
D ₹100

If TR increases from ₹500 to ₹560 when output rises from 10 to 11 units, MR equals

A ₹6
B ₹50
C ₹60
D ₹560

When a firm faces a perfectly elastic demand curve, it implies

A The firm can set any price
B The firm sells all output at one market price
C MR is always less than AR
D TR must be maximum

Under perfect competition, AR equals

A Price
B Marginal cost
C Total cost
D Profit

Under perfect competition, the relationship between AR and MR is

A MR > AR
B MR < AR
C MR = AR
D MR = 0

In a monopoly, the firm’s demand curve is

A Perfectly elastic
B Downward sloping
C Vertical
D Horizontal

Under monopoly, MR is

A Equal to AR
B Greater than AR
C Less than AR
D Zero at all outputs

Under monopoly, MR curve lies

A Above AR curve
B Below AR curve
C On the same curve as AR
D Always on the X-axis

The marginal revenue becomes negative when

A TR is rising
B TR is constant
C TR is falling
D AR is rising

Total revenue is maximum when

A MR is maximum
B MR = 0
C AR = 0
D MC = 0

In perfect competition, TR increases at a constant rate because

A Price falls with output
B Price rises with output
C Price remains constant
D Cost remains constant

In monopoly, TR curve is typically

A A straight line through origin
B Inverted U-shaped
C Horizontal line
D Vertical line

If AR falls as output rises, then

A MR is constant
B MR is greater than AR
C MR falls faster than AR
D MR becomes equal to cost

In monopolistic competition, the firm faces

A Perfectly elastic demand
B Downward sloping demand
C Vertical demand
D Upward sloping demand

In monopolistic competition, MR is generally

A Equal to AR
B Greater than AR
C Less than AR
D Always zero

When a firm reduces price to sell additional units, MR becomes smaller because

A Output rises too slowly
B Revenue from previous units falls
C Cost rises immediately
D Demand becomes vertical

If AR is constant, then MR will be

A Greater than AR
B Less than AR
C Equal to AR
D Negative

Which revenue curve is always equal to price per unit?

A TR
B AR
C MR
D Profit

If price is ₹15 and output is 8 units in perfect competition, MR equals

A ₹8
B ₹15
C ₹120
D ₹0

A firm can have positive MR while AR is falling because

A TR is still increasing
B TR is always decreasing
C Output is fixed
D Cost is constant

When MR is positive, TR must be

A Falling
B Constant
C Increasing
D Negative

When MR is zero, TR is

A Minimum
B Maximum
C Negative
D Constant at zero

A downward sloping AR curve indicates the firm has

A No control over price
B Some control over price
C Perfect elasticity
D Zero market power

In monopoly, MR can be negative when

A Demand is elastic
B Demand is unitary elastic
C Demand is inelastic
D Demand is perfectly elastic

The relationship between AR and MR in a straight-line downward sloping demand curve is that MR

A Lies above AR and has same intercept
B Lies below AR and has same intercept
C Lies below AR and has twice the slope (cuts quantity axis at half)
D Lies above AR and cuts quantity axis at half

If AR curve intersects the quantity axis at 40 units, MR curve intersects it at

A 80 units
B 20 units
C 40 units
D 10 units

In perfect competition, the MR curve is

A Upward sloping
B Horizontal at market price
C Vertical
D Inverted U-shaped

Total revenue is zero when

A Price is maximum
B Quantity is maximum
C Quantity is zero
D MR is maximum

Average revenue falls when

A The firm is a price taker
B The firm faces downward sloping demand
C Price is constant
D Output is fixed

A firm will experience AR = MR when

A It has monopoly power
B It is under perfect competition
C Demand is downward sloping
D It practices price discrimination always

In a monopoly, AR curve is also called

A Supply curve
B Market demand curve
C Marginal cost curve
D Average cost curve

When MR is less than AR, it implies

A Price is constant
B Firm is reducing price to sell more
C Demand is perfectly elastic
D Firm is price taker

Which revenue concept is most important for profit-maximizing output decision?

A Total revenue
B Average revenue
C Marginal revenue
D Fixed revenue

If MR is greater than MC, a firm should

A Reduce output
B Increase output
C Stop production
D Maintain output

If MR is less than MC, a firm should

A Increase output
B Decrease output
C Keep output unchanged
D Increase price only

Profit is maximized when

A TR is maximum
B MR = MC and MC cuts MR from below
C AR = AC
D TC is minimum

A firm earns normal profit when

A AR > AC
B AR < AC
C AR = AC
D MR = 0

Supernormal profit exists when

A AR = AC
B AR > AC
C AR < AC
D MR = MC only

Loss occurs when

A AR > AC
B AR = AC
C AR < AC
D MR = 0

Under perfect competition, a firm’s AR curve is

A Downward sloping
B Horizontal
C Upward sloping
D Vertical

Under monopoly, MR becomes zero at output where demand elasticity is

A Perfectly elastic
B Elastic (greater than 1)
C Unitary elastic (equal to 1)
D Inelastic (less than 1)

In general, MR is positive when demand is

A Inelastic
B Unitary elastic
C Elastic
D Perfectly inelastic

MR is negative when demand is

A Elastic
B Unitary elastic
C Inelastic
D Perfectly elastic

For a monopolist, reducing price to increase output always makes MR lower because

A Costs rise instantly
B Price cut applies to all earlier units
C Demand becomes perfectly elastic
D Revenue becomes fixed

Which statement is true about TR, AR and MR?

A AR is always greater than TR
B MR can be negative even if AR is positive
C MR is always equal to AR
D TR is always constant

If AR is ₹12 and MR is ₹12, the firm is most likely operating under

A Monopoly
B Monopolistic competition
C Perfect competition
D Oligopoly with price leadership

The key reason MR differs from AR under imperfect competition is

A Uniform price always rises
B Firm must lower price to sell extra units
C Costs remain constant
D Output cannot change
