Four staff members at a certain company worked on a project.  The amounts of time that the four staff members worked on the project were in the ratio 2 to 3 to 5 to 6.  If one of the four staff members worked on the project for 30 hours, which of the following CANNOT be the total number of hours that the four staff members worked on the project?

 

A.     80

B.      96

C.      160

D.     192

E.      240

答案是E，我觉得应该是D啊。假设工作了30hours的是那个比例中的2，这不答案就是E了嘛
