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. Lowest Common Multiple 60: 2 x 2 x 3 x 5 - 72: 2 x 2 x 2 x 3 x 3 - LCM: 2 x 2 x 2 x 3 x 3 x 5






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






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






4. 45-45-90 triangle basic lengths of sides






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






6. Average Rate: Average A per B






7. Percent increase = ?






8. 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.






9. Combined Events: E or F






10. Sq. rt(2)

15. How do you multiply roots together.






16. Odd and Even rule.






17. Odd Factors






18. 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






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






20. Volume of a sphere






21. Work problem rule






22. Net






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






24. 30-60-90 triangle basic lengths of sides






25. Sum of consecutive numbers

27. x^r/s = ?






28. 1/6 = what %






29. The number of outcomes that result in A divided by the total number of possible outcomes.






30. (1/4)^2






31. Probability and Geometry.






32. Three triangle length patterns






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






34. 2nd Rule of Probability: P(E) = 1 - P(not E)






35. 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?






36. How to find all divisors of a number






37. Permutations: Order Matters






38. Average Rate: Average speed






39. 5/6 = what %






40. Indistinguishable events how to find the number of permutations

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






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

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






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






48. What does the Sum of the angles in a Regular Polygon formula look like?






49. Multiples of 3






50. 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?
