  7月17GRE数学真题及答案

  数学部分

  直接计算题

  1. According to a tax rate formula for a certain year, the amount of tax owed by an individual whose annual income was between $31,850 and $77,100 was equal to a base tax of $4,386 plus 24 percent of the annual income that exceeded $31,850. According to this formula, what was the amount of tax owed by an individual whose annual income that year was $42,000?

  答案:6822

  解析:题干问,某一年个人收入在$31,850到$77,100之间的税收计算方式为$4,386加上超出$31,850部分的24%。问收入为$42,000的个人这一年需缴纳多少税?

  所以我们可以得到所缴税的计算方式=4386+24%*(42000-31850)=6822.

  大小比较题

  2. x=2, y=3,z=5

  Quantity A: x^-1*y*z^-2

  Quantity B: (y/xz)^2

  A. Quantity A is GREater.

  B. Quantity B is greater.

  C. The two quantities are equal

  D. The relationship cannot be determined from the information given.

  答案:A

  解析:A的值= x^-1 * y * z^-2=1/2*3* 1/25=3/50

  B的值= =(y/xz)^2=9/100

  因为A=0.06,而B=0.09,所以A>B.

  3. x < y-2

  Quantity A: The average (arithmetic mean) of x and y

  Quantity B: y-1

  A. Quantity A is greater.

  B. Quantity B is greater.

  C. The two quantities are equal

  D. The relationship cannot be determined from the information given.
