In an office, Each and Every person likes tea or coffee, 70% of the people like tea, and 50% like coffee. Find the percentage of people who likes only tea?
Answer & explanation
Correct answer: option 2
*If each and every person like something, then more than 100% of people like both*.
ATQ,
Tea + Coffee = 70% + 50% = 120%
So, Percentage of person who like both = 120% - 100% = 20%
⇒ Only tea likes = 70% - 20% = 50%
