Answer:
you should hold <u>76</u> shares of stock per 100 put options to hedge your risk.
Explanation:
Current stock price, S = $85
Risk-free rate of return, r = 5%
Standard Deviation, v = 25%
Exercise price, X = $90
expiration date, t (in years) = 30 days = 1 month = 1/12 = 0.083333 years
The option price (OP) is given by the formula:

![d_1 = [ln(S/X) + (r + v^{2} /2)t]/vt^{0.5}\\d_1 = [ln(85/90) + (0.05 + 0.25^{2} /2)*0.08333]/(0.25*0.08333^{0.5})\\d_1 = -0.6982](https://tex.z-dn.net/?f=d_1%20%3D%20%5Bln%28S%2FX%29%20%2B%20%28r%20%2B%20v%5E%7B2%7D%20%2F2%29t%5D%2Fvt%5E%7B0.5%7D%5C%5Cd_1%20%3D%20%20%5Bln%2885%2F90%29%20%2B%20%280.05%20%2B%200.25%5E%7B2%7D%20%2F2%29%2A0.08333%5D%2F%280.25%2A0.08333%5E%7B0.5%7D%29%5C%5Cd_1%20%3D%20-0.6982)

Using the pro-metric calculator for the cumulative normal distribution:
N(-d1) = N(- (-0.6982)) = N(0.6982) = 0.75747
N(-d2) = N(-(-0.7704)) = N(0.7704) = 0.77947

![OP =[ 90e^{(-0.05*0.08333)} * 0.77947] - (85*0.75747)\\OP = 5.48](https://tex.z-dn.net/?f=OP%20%3D%5B%2090e%5E%7B%28-0.05%2A0.08333%29%7D%20%2A%200.77947%5D%20-%20%2885%2A0.75747%29%5C%5COP%20%3D%205.48)
Note that N(-d₁) = 0.76
This means that 76/100 (i.e to hedge your risk, you should hold 76 per 100 put options )
The correct answer is A = 110, B= 40, C=20..
<u>Explanation</u>
If A+B-C= 170 and B+C-A=130 ,
=C+A = 130
or, C= 130- A
Again, A+B-C =170
or, A+B =170+C
A+B = 170+130-A ( c=130-A)
A+B = 300-A
2A+B = 300
A+B= 300/2
A+B = 150
A+B-C= 170
A+B = 170+C
150 = 170 +C ( A+B = 150)
or, C = 20..............................(1.)
A+C =130
or,A+ 20= 130 ( A=110).....................(2)
A+B = 150
110+B= 150
B = 150-110
B= 40..........................................(3)
Therefore, A = 110, B= 40, C=20..
Answer:
