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.

9. The average of 5 numbers is 2. After one number is deleted - the new average is -3. What number was deleted?






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






11. The average of consecutive numbers






12. Simple Interest formula (remember this is only the interest earned - not the total amount of money present in the bank after interest earned)






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






14. 2n - 2n+2 - 2n+4






15. 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






16. Combined Events: E or F






17. x^r/s = ?






18. Sq. rt(3)






19. Permutations: Order Matters






20. Simple probability






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






22. Sq. rt(2)






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






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






25. Multiplication principle






26. 1/6 = what %






27. Set Problems formula






28. Properties of 0






29. 2nd Rule of Probability: P(E) = 1 - P(not E)






30. Percent Formula






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






32. Always try to factor






33. Average Rate: Average speed






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






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






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






37. 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?






38. Gross Profit formula






39. Volume of a sphere






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






41. 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.






42. 5/6 = what %






43. Price purchased for by wholesaler






44. Intersecting Sets






45. gcd(m,n)






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






47. 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.






48. Inscribed Angle - Minor Arc






49. Triangle abc with d on the outside with a line. What does d = ?






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