  1. 21 people do not like mangoes because if you had 15 like mangoes and 21 like pineapples, people that selected pineapples do not like mangoes. Same goes for pineapple, if 15 people selected mangoes as their favorite, then 15 people do not like pineapples.

  2. 37.5% people only like mangoes. (Divide #15/100 = 0.375# then move decimal by 2 places.
