If the total price of n equally priced shares of a certain stock was $12,000, what was the price per share of the stock? (1) If the price per share of the stock had been$1 more, the total price of the n shares would have been $300 more. (2) If the price per share of the stock had been$2 less, the total price of the nshares would have been 5 percent less.

Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.

Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.

BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

EACH statement ALONE is sufficient.

Statements (1) and (2) TOGETHER are NOT sufficient.

##### 考题讲解

（1）    n(x+1)=12000+300，即nx+n=12000+300，n=300，代入nx=12000解得x=40，题目得解。

（2）    n(x-2)=12000*(1-0.05)，即nx-2n=11400，因为nx=12000，解得n=300，代入nx=12000解得x=40，题目得解。
