A. 395,808 B. 420,000 C. 447,888 D. 496,800 E. 645,795 lets X = original number of cars 24% more than X can be written as 1.24*X = 520800 X = 420000 Hence option B is correct

A. 395,808 B. 420,000 C. 447,888 D. 496,800 E. 645,795 We are given that the number of cars in city X this year is 520,800, which is 24% more than there were in city X last year. If we let the number of cars in city X last year = c, we can create the following equation: 520,800 = 1.24c c = 420,000 Answer: B

Hi All, We're told that the number of cars in city X this year is 520,800 and that total is 24% more than there were in city X last year. We're asked for the number of cars that were there in city X last year. While the numbers in this prompt are not 'pretty', the answer choices are 'spaced out' enough that we can do a bit of estimation and some 'brute force' math to get to the answer. To start, 24% of 100,000 = 24,000 (so a 24% increase would be 124,000 total cars). Thus, we can quickly map out increases of 100,000 cars... 200,000 + 48,000 = 248,000 300,000 + 72,000 = 372, 000 400,000 + 96,000 = 496,000 500,000 + 120,000 = 620,000 Since 520,800 is far closer to 496,000 than it is to 620,000, the total number of cars last year would be a bit more than 400,000. There's only one answer that matches... Final Answer: GMAT assassins aren't born, they're made, Rich
