|Quantity A||Quantity B|
|No. of male attendees who wore mask||800|
- A. Quantity A is greater.
- B. Quantity B is greater.
- C. The two quantities are equal.
- D. The relationship cannot be determined from the information given.
Given that the total attendees are 4000.
No. of attendees wore a mask = 40% of 4000 = 1600, So 2400 people didn’t wear the mask.
No. of males = 70% of 4000 = 2800
So, no. of females = 1200
For 2 sets question, use table method,
|Female||10% of 1200 = 120||1200|
From the table, we can find
|Female||1080||10% of 1200 = 120||1200|
So, No. of men who wore mask = 520
Quantity B is greater than Quantity A.
Hence the answer is B.
