Three questions from this test

Taken from the banks above, with the worked answers, so you can see the level before you start the clock.

1 Medium ≈ 75th percentile
Compare the two quantities.

x>0x>0

Quantity Axx+1\dfrac{x}{x+1}
Quantity Bx+1x+2\dfrac{x+1}{x+2}
  1. Quantity A is greater.
  2. Quantity B is greater.
  3. The two quantities are equal.
  4. The relationship cannot be determined from the information given.
Show answer
Answer: B. Quantity B is greater.
Cross-multiply (all denominators positive): compare x(x+2)=x2+2xx(x+2)=x^2+2x with (x+1)2=x2+2x+1(x+1)^2=x^2+2x+1. B is larger by 1(x+1)(x+2)\tfrac{1}{(x+1)(x+2)} for every positive xx.
35 Medium ≈ 80th percentile
Compare the two quantities.
Quantity AThe standard deviation of 2, 4, 6, 8, 10
Quantity BThe standard deviation of 12, 14, 16, 18, 20
  1. Quantity A is greater.
  2. Quantity B is greater.
  3. The two quantities are equal.
  4. The relationship cannot be determined from the information given.
Show answer
Answer: C. The two quantities are equal.
The second list is the first shifted by 10. Shifting moves the mean but not the spread, so the standard deviations are equal.
69 Easy ≈ 65th percentile
What is the positive difference between the two solutions of x2−10x+21=0x^2-10x+21=0?
Show answer
Answer: 44
x2−10x+21=(x−3)(x−7)x^2-10x+21=(x-3)(x-7), so the solutions are 3 and 7, and they differ by 4.

How it is scored

Every question is marked right or wrong as you go; there is no partial credit, exactly as in the real thing. At the end you get your score, the time you used against the time allowed, your average per question, and your accuracy broken down by percentile level, so you can see whether the ceiling is difficulty or speed. Every question then comes back with your answer, the correct one and a full worked solution.
