Cost (or MV) of each share = FV of each share + Premium = Rs 50 + Rs 100 = Rs 150
Number of shares purchased = 200
∴ Amount invested = Cost of each share \times Number of shares purchased
= Rs 150×200 = Rs 30,000
total dividend received = Number of shares purchased \times Dividend received on each share
= 200×(50100×50) = Rs 5,000
Selling price of each share at discount of Rs 10 = Rs 50 - Rs 10 = Rs 40
Selling price of 100 share at discount of Rs10=Rs.40×100=4000
∴ Selling price of each share at premium of Rs 75 = Rs 50 + Rs 75 = rs 125
∴ Selling price of 100 shares at premium of Rs 75 = Rs 125×100 = Rs 12,500
Total money received on selling 200 shares = Rs 4,000 + Rs 12,500 = Rs 16,500
Brokerage paid on each trade = rs 20
∴ Total brokerage paid on 3 trades,
= Rs 20×3 = Rs 60
Net income of Mr. D'souza = Total money received on selling 200 shares + Total dividend received - Total brokerage paid on 3 trades
= Rs 16,500 + Rs 5,000 - Rs 60
= Rs 21,440
Since net income of Mr. D'souza is less than the amount invested so Mr. D'souza incurred a loss.
Loss incurred = amount invested - Net income of Mr. D'souza
= Rs 30,000 - Rs 21,440 = Rs 8,560.
Thus, Mr. D'souza incurred a loss of Rs 8,560.
