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






2. Net






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






4. Quadratic formula






5. Simple probability






6. Circular permutation: The number of ways to arrange n distinct objects along a fixed circle is?






7. Prime Factorization to find Greatest Common Factor






8. 1/6 = what %






9. Permutations: Order Matters






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

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






18. 0! = ?






19. Gross






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






21. 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.






22. gcd(m,n)






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

25. Number added or deleted






26. 1/8 = what %

33. 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?






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