Explanation:

Total shares bought=$40000/$250=160 shares

Interest on amount borrowed=8%*$20000=$1600

When the price falls by 7% the new price =$250(1-0.07)=$232.50

Hence rate of return=(New price*number of shares-Interest-total investment)/initial investor's funds

=($232.50*160-$40000-$1600)/$20000=-22%

Initial margin=investor's money/total investment=$20000/$40000=50%

maintenance  margin=30%

Margin call price=Current price x (1- initial margin)/ (1- maintenance margin)

                           =$250*(1-0.5)/(1-0.3)

                           =$178.57
