A company has two models of computers, model X and model Y. Operating at a constant rate, a model X computer can complete a certain task in 72 minutes and a model Y computer can complete the same task in 36 minutes. If the company used the same number of each model of computer to complete the task in 1 minute, how many model X computers were used?	Choose the correct choice
A) 22	B) 23	C) 24	D) 25	E) 26
Let's say 1 work is processing 72 gb of data.   Model X : 1 gb per min   Model Y : 2 gb per min   Working together, 1 X and 1 Y = 3 gb per min   So, 24 times as many computers would work at 72 gb per min.   So no. of X =24   Answer is 24
