This person owns:

400 shares of Stock A500 shares of Stock B

Explanation:

The person initially has $55,000 invested in stock A and B and they are priced at $50 and $70 respectively, in other words:

55000 = 50A + 70B

Where:

A is the quantity he owns of stock AB is the quantity he owns of stock B

Time goes by and the value of A stock goes up %50. This means that it went up to $75, because %50 of 50 is 25, and 25 + 50 is 75.

Also, stock B doubles in value, so it is now selling at $140 and his investment is now worth $100,000, in other words:

100000 = 75A + 140B

We have two equations and two unknowns so we can solve the equations to get the values of A and B:

55000 = 50A + 70B100000 = 75A + 140B

Solve for B on equation 1:

$B=\frac{55000-50A}{70}$

Substitute B on equation 2:

$100000 = 75A + 140\frac{55000-50A}{70} = 75A + 110000-100A=-25A+110000$

Solve A:

$A=\frac{100000-110000}{-25}$ A=400

Now use the value of A in any of the equations to solve for B:

$B=\frac{55000-50(400)}{70}$ B=500

The amount of shares this person owns of stock A is 400 and 500 of stock B.
