A certain business printer can print 100 characters per second, which is 5 times faster than an average printer. If an average printer can print 4 times faster than an electric typewriter, how many characters per minute can an electric typewriter print?
Correct answer: A
Explanation
Rate at which a business printer can print = 100 characters per second
Rate at which an average printer can print = (100/5) characters per second = 20 characters per second
Average printer's rate = 4*Electric typewriter's rate
=>Electric typewriter's rate = 20/4 = 5 characters per second = 5*60 characters per minute = 300 characters per minute
