A company has two models of computers, model M and model N. Operating at a constant rate, a model M computer can complete a certain task in 36 minutes and a model N computer can complete the same task in 18 minutes. If the company used the same number of each model of computer to complete the task in 1 minute, how many model M computers were used? Choose one: A) 12 B) 11 C) 10 D) 9 E) 8
Let's say 1 work is processing 36 gb of data.   Model M : 1 gb per min   Model N : 2 gb per min   Working together, 1 M and 1 N = 3 gb per min   So, 12 times as many computers would work at 36 gb per min.   So no. of M =12   12nswer is 12
