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.

10. Simple probability






11. How to check whether a number is a multiple of 4.






12. Combined Events: E and F






13. Circular permutation: The number of ways to arrange n distinct objects along a fixed circle is?






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






15. 0! = ?






16. gcd(m,n)






17. Sq. rt(3)






18. Price sold for by retailer (after markup)






19. Multiplication principle

24. 45-45-90 triangle basic lengths of sides






25. The average of consecutive numbers






26. Average Rate: Average speed






27. Formula for area of a Trapezoid






28. Inscribed Angle - Minor Arc






29. 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.






30. 5/6 = what %






31. Permutations: Order Matters






32. 3^3 x 4^3 = ?






33. To determine the number of integers less than 5000 that are evenly divisible by 15...?






34. Multiples of 3






35. Gross






36. 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






37. Sq. rt(2)






38. Dependent events: When are two events said to be dependent events?

41. Compound interest rule






42. 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.






43. What to do with equations that have fractions






44. Odd Factors
