(A) 360 (B) 480 (C) 576 (D) 720 (E) 1,440 OA E Source: Official Guide We can also solve this question with equivalent ratios We'll first convert 4 minutes to SECONDS in order to use the same units of measurement throughout the solution. 1 minute = 60 seconds So, 4 minutes = 240 seconds. Now let's set up and equation using the ratio # of copies/time in seconds Let x = the number of copies made in 4 minutes (aka 240 seconds) We get: 2/(1/3) = x/240 Cross multiply to get: (1/3)(x) = (2)(240) Simplify: x/3 = 480 Multiply both sides by 3 to get: x = 1440 Answer: E Cheers, Brent _________________ Brent Hanneson â€“ Creator of GMATPrepNow.com Use our video course along with Sign up for our free Question of the Day emails And check out all of our free resources GMAT Prep Now's comprehensive video course can be used in conjunction with Beat The GMATâ€™s FREE 60-Day Study Guide and reach your target score in 2 months! ### GMAT/MBA Expert GMAT Instructor Joined 25 Apr 2015 Posted: 1651 messages Followed by: 14 members Upvotes: 43 BTGmoderatorDC wrote: If a photocopier makes 2 copies in 1/3 second, then, at the same rate, how many copies does it make in 4 minutes? (A) 360 (B) 480 (C) 576 (D) 720 (E) 1,440 The rate of the photocopier is 2/(1/3) = 6 copies per second, so in 4 minutes, or 240 seconds, it can make 6 x 240 = 1,440 copies.
