At a certain baseball game attended by 2,000 people, 800 people like eating popcorn, and 300 people like eating both popcorn and peanuts. At most, how many people like eating peanuts?
Let Peanuts = N and Popcorn=C
People who don’t eat Peanuts= Not N= 800-300=500
......................N.............Not N.....................Total
C.................. 300 ......... (500) ................... 800
Not C .......... —— .......... —— .................... (1200)
Total ........... —— .......... —— ....................... 2000
(1) At least 700 people do not like eating popcorn or peanuts.
We are asked to find maximum number of people who eat Peanuts(N), so we take the least possible people.
......................N.............Not N.....................Total
C.................. 300 ......... (500) ................... 800
Not C .......... (500) .......... 700 .................... (1200)
Total ........... (800) .......... —— ....................... 2000
At most, 800 people like eating Peanuts.
