53. In the store of a car dealer, less than 10 cars are equiped with fog light, and 40% of the cars have  **window, Is the dealer has more car with fog light than those with **window?

(1)80% cars have fog light and window

(2)52 cars have fog light or window or both

按照我的理解是 C 不知道对不对

80% 有  f 和 w . 52量车 有 f ,w或 f&w

这样是不是可以求出车辆总数.  52* 100/80

然后40%有 W. F少于10.

这样就可以算出来,对吧

I never saw this problem before, but my take is C as well.
