Correct option is C
Given:
In an airline, hot drinks and iced tea were served to 120 passengers. 75 passengers enjoyed hot drinks and 62 enjoyed iced tea. If 40 enjoyed both.
Solution:
Total passengers = 120
Total Passengers enjoy beverage = (Enjoyed hot drinks) + (Enjoyed iced tea) − (Enjoyed both)
Total Passengers enjoy beverage = 75 + 62 - 40
Total Passengers enjoy beverage = 97
Passengers enjoyed none of the beverages = Total passengers − Total Passengers enjoy beverage
Passengers enjoyed none of the beverages = 120 - 97 = 23
23 passengers enjoyed none of the beverages.
Thus, the correct answer is (c).
Alternative Method:
Total passengers = 120
Only Hot drinks = 75 - 40 = 35
Only Ice tea = 62 - 40 = 22
Total beverage = 25 + 40 + 22 = 97
None of the beverages = 120 - 97 = 23
Thus, the correct answer is (c).
