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.

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






3. gcd(m,n)






4. Inscribed Angle - Minor Arc






5. 2nd Rule of Probability: P(E) = 1 - P(not E)






6. How to check whether number is multiple of 9






7. How to find the slope.






8. Probability and Geometry.






9. 2n - 2n+2 - 2n+4






10. How do you multiply roots together.






11. 1/6 = what %






12. Formula for area of a Trapezoid






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






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






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






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






19. 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.






20. 4th rule of Probability






21. 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?






22. Always try to factor






23. 3^3 x 4^3 = ?






24. 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.
