If the only stocks that an investor owns are 75 shares of stock A and 100 shares of stock B , what is the total dollar value of his stocks?

Question: 75A+100B=25(3A+4B)=? Where A and B are the prices of the stock A and stock B receptively. As you can see, basically we should find the value of 3A+4B.

(1) The total value of 3 shares of stock A and 4 shares of stock B is $160 --> 3A+4B=$160. Sufficient.

(2) The value of each share of stock A is twice the value of each share of stock B --> A=2B --> 3A+4B=10B, we need the value of either A or B. not sufficient.

Answer: A.

P.S. You should always indicate OA if you have it.
