Question 9: In a meeting the number of persons who ordered coffee is 50 and the number of persons who ordered tea is 40. Total number of persons who ordered none is half the number of persons who ordered tea. Find the percentage of persons who does not ordered anything in the meeting. Assuming only these three types of persons in the meeting. A.33.36% B.18.18% C.20% D.15%
Basic Answer
Step 1: Determine the number of persons who ordered nothing
Given:
- Number of persons who ordered coffee = 50
- Number of persons who ordered tea = 40
- Number of persons who ordered none = Half the number of persons who ordered tea
Calculation:
Number of persons who ordered none = 40 / 2 = 20
Step 2: Calculate the total number of persons in the meeting
Total number of persons = Number of persons who ordered coffee + Number of persons who ordered tea + Number of persons who ordered none
Calculation:
Total number of persons = 50 + 40 + 20 = 110
Step 3: Calculate the percentage of persons who ordered nothing
Percentage of persons who ordered nothing = (Number of persons who ordered none / Total number of persons) * 100
Calculation:
Percentage of persons who ordered nothing = (20 / 110) * 100 ≈ 18.18%
Final Answer
The percentage of persons who did not order anything in the meeting is approximately 18.18%, which corresponds to option B.
