Choose the correct choice from the following:	A) 480	B) 96	C) 160	D) 192	E) 320
A:B:C:D=2x:3x:5x:6x, for some positive number x. Total time 2x+3x+5x+6x=16x.   If 2x 2 +3 +5 +6=

16x.   If 2x= 60 then 16x = 480;   If 3x = 60 then 16x = 320;   If 5x = 60 then 16x = 192;   If 6x = 60 then 16x = 160;   Only answer choices which is not obtained is 96.   Answer: 96.
