Price = $20
Quatity = 50kg

The firm’s profit = Total revenue – total cost = TR – TC
TR = price x quatinty sold
= $20 x 50
= $1000
TC = $12 x 50
= $600
Profit = $(1000-600)
= $400

Normal profit

Because it is equal to demand curve of a firm and demand of perfectly elastic
AR = MR = MC = Demand & supply Curve

(i) Both are falling at initial stage
(ii) Both of them are rising after they intersect at price of $10 and quantity of 40kg

Balance of trade = Total visible
Export – total visible = Import
Visible Exports = $m
Agriculture = 200
Minefal produce –
Capital goods –
Total $500

Visible Import: – $m
Agriculture –
Mineral produces –
Consumer goods 250
Capital goods 400
Total $650

Therefore Balance of trade = $500 – $650
Balance of trade = $150
It is unfavourable Balance of Trade because total visible export is less than the total visible import

Invisible Trade Balance = Total Invisible Export – total
Visible Import –
Invisible Export – $m
Insurance – 25
Banking – 30
Transportation – 25
Total $80

Invisible Import – $m
Insurance – 50
Banking – 75
Transportation – 85
Total = $210
Therefore invisible Trade balance = $80 – $ 210
= -$130
i.e – $130
it is an unfavourable invisible trade balance total invisible import is more than total invisible export

Balance of current Balance = value of total Export – Value of total Import
Total Export – $m
Agriculture – 200
Mineral produce – 300
Consumers goods –
Capital goods –
Insurance – 25
Banking – 30
Transportation – 25
Total = $580

Total Imports: – $m
Agriculture –
Mineral produce –
Consumer goods 250
Capital goods – 400
Insurance – 50
Banking – 75
Transport – 85
Total = $860
Therefore 580 – 860 = $280
It is a deficit current Account balance
