Say x people own both cars.

(16 - x) + (11 - x) = 15 --> x = 6.

Answer: B.

Think about it logically:
16 people own Fords and 11 own Toyotas. So maximum 11 people can own both which means at least 5 people will own only one car (only Ford). If you want 15 people to own only one car, you need to remove 10 people from the overlap of 11. For every one overlap, there are 2 people so if you remove 5 overlaps, you get 10 people who should own a single car. You are left with 6 overlaps.

A good questions that tests mindfulness.

You clearly see the difference of 12 between 15 and 27 -> (16+11). But it takes concentration to realize that those 12 are number of vehicles and not number of owners. To get the latter, we have to divide by 2.

Hope it helps!
