![]() In April, the store sold twice the number of roses that it sold in March, and three times the number of lilies that it sold in March. In March, the store sold twice as many roses as lilies. A certain florist shop sells only roses and lilies.Select one answer from the list of five answer choices. The correct answer- (D) Multiple choice – Frequently asked GRE Math Questions However, in this example, the amounts are equal.Ĭhoice (A) can now be removed since Quantity A is not always larger. ![]() These values, once again, satisfy the problem’s equation. Try something less typical when picking the second set of integers, such as making a = b = 1. In this case, Quantity A is greater.Ĭhoices (B) and (C) can be removed since Quantity B is not always greater and the two amounts are not always equal.Īfter that, experiment with other numbers. These numbers satisfy the equation as 8 2 = 4 3 = 64. The correlation cannot be identified based on the data providedĪnswer- (D) The correlation cannot be identified based on the data provided.Ĭhange a and b to different integers that meet the equation a 2 = b 3, such as a = 8 and b = 3.To solve, cross-multiply to get 71x + 71 = 70x + 75. Next, simplify to find that x = 4. Therefore, Quantity B is greater. Substituting this information into the formula gives: 71= 70x + 75 / x + 1 ![]() In this formula, 71 is the average, 70x + 75 is the total, and there are x + 1 days. Next, find the value of x using the formula for average– Average = Total / Number of Items Hence, the sum of the high temperatures will be 70x + 75 (including the additional day with a temperature of 75 degrees). If the average high temperature for x days is 70 degrees, then the sum of those x high temperatures is 70x. The addition of one day with a high temperature of 75 degrees increases the average to 71 degrees.
