Section C (4 Mark)

An investor purchased on margin Alpha Computer for Rs. 30/- a share. The stock's price subsequently rose to Rs. 50/- a share at which time the investor sold the stock. If the margin requirement is 60 percent and the interest rate on borrowed funds was 7 percent, what would be the percentage earned on the investor's funds (excluding commissions)? What would have been the return if the investor had not bought the stock on margin?
