GMAT Math Ultimate Review 2023 Common Factors - ANS-Break down both numbers to their prime factors to see what factors they have in common. Multiply all combinations of shared prime factors to find all common factors. Gross Profit - ANS-Gross profit = Selling Price - Cost Combined Events - ANS-For events E and F: • not E = P(not E) = 1 - P(E) • E or F = P(E or F) = P(E) + P(F) - P(E and F) • E and F = P(E and F) = P(E)P(F) Multiplication Principle - ANS-The number of ways indepe...

Angles that look the same can be assumed to be the same, even if you can't prove it, since there is no other way to solve it. For example, ACD can be assumed to be 25° - Answer You are asked to solve for DBC and are stuck. What might be a reasonable assumption to help solve it? Just from eyeballing it, the answer is greater than 180, which is a straight line. It also seems less than 270, which would leave only a 90° angle. 252° is a reasonable answer. - Answer What answer seems most rea...
