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. 3^3 x 4^3 = ?






2. 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.






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

12. 1/8 = what %






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






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. How to find all divisors of a number






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

32. gcd(m,n)






33. Prime Factorization to find Greatest Common Factor






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






35. 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.






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






37. Sq. rt(2)






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

48. Number added or deleted






49. Compound interest formula






50. If $10 -000 is invested at 10% annual interest - compounded semi-annually - what is the balance after 1 year?
