In an office, Each and Every person likes juice or coffee, 80% of the people like juice, and 55% like coffee. Find the percentage of people who likes only coffee?
Answer & explanation
Correct answer: option 3
*If each and every person like something, then more than 100% of people like both*.
ATQ,
juice + Coffee = 80% + 55% = 135%
So, Percentage of person who like both = 135% - 100% = 35%
⇒ Only Coffee likes = 55% - 35% = 20%
