If 75 percent of the guests at a certain banquet ordered dessert…Why not D is the answer ?
If 75 percent of the guests at a certain banquet ordered dessert, what percent of the guests ordered coffee?
(1) 60 percent of the guests who ordered dessert also ordered coffee.
(2) 90 percent of the guests who ordered coffee also ordered dessert.
Hi Prem,
The answer here is not D, since you cannot consider that all 100% of the guests ordered dessert, coffee or both. You can have some guests who ordered neither.
Hope this helps!
