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. gcd(m,n)*lcm(m,n)






2. 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?






3. Formula for Mixed Group problems (involving Both/Neither)






4. Combined Events: Not E = P(not E) = ?






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






6. Odd and Even rule.






7. How to check whether number is multiple of 9






8. Combined Events: E and F






9. Simple Interest Formula (remember this is the total amount of money in the bank after the interest is earned)






10. Price purchased for by wholesaler






11. Gross Profit formula






12. How to find all divisors of a number






13. How do you multiply roots together.






14. 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






15. Permutations: Order Matters






16. 1/6 = what %






17. Work problem rule






18. Compound interest formula






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






20. 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?






21. Multiplication principle






22. Sum of consecutive numbers

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






26. Quadratic formula






27. x^r/s = ?






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






29. Net






30. 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.
