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. If $10 -000 is invested at 10% annual interest - compounded semi-annually - what is the balance after 1 year?






2. Some GMAT word problems involve groups with distinct 'either/or' categories (male/female - blue collar/white collar - etc.) The key is to do what with the information? 1. Find total number of possible outcomes. 2. Find the number of desired outcomes.






3. The average of consecutive numbers






4. Combined Events: E and F






5. To determine multiple-event probability where each individual event must occur in a certain way.






6. How to check whether a number is a multiple of 12.






7. How many liters of a solution that is 10% alcohol by volume must be added to 2 liters of a solution that is 50% alcohol by volume to create a solution that is 15% alcohol by volume?






8. Permutations: Order Matters






9. 2n+1 - 2n+3 - 2n+5






10. Number of integers from A to B inclusive = B - A + 1 - How many consecutive integers are there from 73 through 419 - inclusive?






11. (1/4)^2






12. Compound interest formula






13. Number added or deleted






14. How to check whether a number is a multiple of 3.






15. If you have to guess in a problem - which ones should you guess? Especially if you have to plug numbers.






16. The number of ways independent events can occur together.






17. 1. A and B < A or B 2. A or B > Individual probabilities of A - B 3. P(A and B) = P(A) x P(B) <-- 'fewer options' 4. P(A or B) = P(A) + P(B) <-- 'more options' - Probability of multiple events rules.






18. Inscribed Angle - Minor Arc






19. 2nd Rule of Probability: P(E) = 1 - P(not E)






20. 3rd Rule of Probability: Conditional Probability






21. When you see an equation in factored form in a question?

23. Odd Factors






24. Properties of 0






25. Three triangle length patterns






26. Think of averages as what? The average of 3 - 4 - 5 - and x is 5. What is x? 3 is 2 less than 5 4 is 1 less than 5 - 5 is the average - x = 5 + 3 = 8






27. In general - difficult questions require how many steps to solve?






28. Percent increase = ?






29. Prime Factorization to find Greatest Common Factor






30. How many liters of a solution that is 15% salt must be added to 5 liters of a solution that is 8% salt so that the resulting mixture is 10% salt?
