7.

- D.Slopes upward
10.
When price falls to sell more, the MR curve lies:

11.

Section B — Challenge / Olympiad (2 marks each)
10 × 2 = 20 marks
16.
A wheat farmer in a perfectly competitive market can sell any amount at the going price of ₹20/kg. For him, AR and MR are:
- A.Both ₹20 and constant
- B.Falling steeply
- C.Both zero
- D.Above ₹20
17.

- A.₹6
- B.₹24
- C.₹8
- D.₹2
18.
Because AR equals price, the firm's AR curve is identical to its:
- A.Demand curve
- B.Cost curve
- C.Supply curve

19.

- B.Raise the price
- C.Keep price fixed
- D.Increase fixed cost
20.
As a firm with a downward demand curve keeps increasing sales, TR will eventually:

- B.Rise forever
- C.Stay constant
- D.Become negative immediately
21.
If selling more units leaves total revenue unchanged, the marginal revenue of those units is:

22.
The horizontal AR = MR line of a competitive firm reflects that the firm is:

- B.Fixed cost
- C.Average fixed cost
- D.Total revenue only
