Brain Teaser
Festus hired Buford to work the drive through window at his new restaurant
“Critter-on-a-Stick”
Every “Varmint Meal” is supposed to contain 4 items . . .
- Critter
- Stick
- RC Cola
- Fried fat chips
At the end of the first day Buford served exactly 100 Varmint Meals, but he made the following errors
- 70 meals contained no Critter
- 75 contained no stick
- 85 contained no RC Cola
- 80 contained no fried fat chips
What is the minimum number of Varmint Meals that contained none of the 4 items? (The customer left with an empty sack).
The answer is . . . 10
Add up all the errors, and you find that 100 Varmint Meals were missing a total of 310 parts.
That total means that, at a minimum, 100 meals were missing 3 parts, and 10 (the remainder when dividing 310 by 100) must have missed all 4 parts.
On the flip side, as many as 70 may have missed all 4 parts.
John Medora wrote that it may be easier to understand if you
count the number of items served - 30 critters, 25 sticks, 15 colas
and 20 chips. That is a total of 90. Out of 100 bags then
the minimum to be empty is 10 (100-90).
Our Winner is . . .
