Correct option is D
Information Given:
Total people = 100
Like tea = 40
Like coffee = 58
Like both = 26
Total people = 100
Like tea = 40
Like coffee = 58
Like both = 26
Formula Used:
n(A ∪ B) = n(A) + n(B) − n(A ∩ B)
n(A ∪ B) = n(A) + n(B) − n(A ∩ B)
Logic: Find people who like at least one, subtract from total
Step-by-step:
n(Tea ∪ Coffee) = 40 + 58 − 26 = 72
Neither = 100 − 72 = 28
n(Tea ∪ Coffee) = 40 + 58 − 26 = 72
Neither = 100 − 72 = 28
Short Trick:
Total − (Tea + Coffee − Both)
Total − (Tea + Coffee − Both)
Final Answer:
28
