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. Average Rate: Average A per B






2. 0! = ?






3. gcd(m,n)






4. 3rd Rule of Probability: Conditional Probability






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






6. Price purchased for by wholesaler






7. 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.






8. Simple probability






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






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






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






12. Price sold for by retailer (after markup)






13. Compound interest formula






14. The average of consecutive numbers






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






16. Gross






17. Permutations: Order Matters






18. 5/6 = what %






19. Prime Factorization to find Greatest Common Factor






20. Inscribed Angle - Minor Arc






21. 30-60-90 triangle basic lengths of sides






22. 2n - 2n+2 - 2n+4






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






24. How to find all divisors of a number






25. Work problem rule






26. Always try to factor






27. Multiples of 3






28. Percent Formula






29. Properties of 0






30. How to find the slope.






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






32. Net






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






34. 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?






35. Multiplication principle






36. 1/8 = what %






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






38. Sq. rt(3)






39. Odd Factors






40. Combined Events: E or F






41. 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






42. Average Rate: Average speed






43. How do you multiply roots together.






44. Three triangle length patterns






45. Number added or deleted






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






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






48. Set Problems formula
