Out of 100 people, 60 like Tea, 70 like Coffee, and 40 like both. How many people like only Tea or only Coffee?
Show answer & explanation
Correct answer: A
Explanation
Given:
Total people = 100
Tea (T) = 60
Coffee (C) = 70
Both (T ∩ C) = 40
Only Tea = T − Both = 60 − 40 = 20
Only Coffee = C − Both = 70 − 40 = 30
People who like only Tea or only Coffee
= 20 + 30 = 50
Hence, the correct answer is option 1.
