In an office, Each and Every person likes shake or tea, 72% of the people like shake, and 65% like tea. Find the percentage of people who likes only tea?

28

*If each and every person like something, then more than 100% of people like both*.

ATQ,

shake + tea= 72% + 65% = 137%

So, Percentage of person who like both = 137% - 100% = 37%

⇒ Only tea likes = 65% - 37% = 28%
