GMAT Quantitative General

Subjects : gmat, math
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Combined Events: E and F






2. How do you multiply roots together.






3. Trial Problems: look at the probability of NOT OCCURRING






4. 2nd Rule of Probability: P(E) = 1 - P(not E)






5. Since Mieko's average speed was 3/4 of Chan's - her time was 4/3 as long.






6. (1/4)^2






7. In general - medium questions require how many steps to solve?
