Answer:
A. 400 shares
B. 400 shares
Explanation:
You can calculate the amounts required in Requirement A and B by using their formulas given below.
No.of shares you can short = Cash Available/(Initial Margin*Price per share)
No.of shares you can short = 20,000/(50%*100)
No.of shares you can short = 400 shares
Price = Amount borrowed with interest/ No. of shares) / ( 1- Maintenance margin)
Price = (20,000/400)/(1-25%)
Price = 50/0.75
Price = 66.66
