Please, can any expert assist me with it? Thanks in advanced. ### GMAT/MBA Expert GMAT Instructor Joined 04 Oct 2017 Posted: 551 messages Followed by: 11 members Upvotes: 180 Hello LUANDATO. Here, we will use the following formula: $$\left|F\ o\ B\ o\ b\right|=\left|F\right|+\left|B\right|+\left|b\right|-\left(\left|F\ y\ B\right|+\ \left|F\ y\ b\right|+\ \left|B\ y\ b\right|\right)+\left|F\ y\ B\ y\ b\right|$$ where "F" are the people having fries, "B" having burgers and "b" having bacon. Replacing the data, we get $$5=5+4+3-\left(4\right)+\left|F\ y\ B\ y\ b\right|$$ So $$\left|F\ y\ B\ y\ b\right|=0.$$ The correct answer is A . I hope this explanation may help you.
