Question

Mr Tokai is very particular in how he makes his coffee. He is completely inflexible in that he can only take 1 teaspoon of coffee with 2 teaspoons of sugar. Any more coffee or sugar given to him is discarded in his quest for the perfect coffee. Suppose you give him 9 teaspoons of coffee and 2 teaspoons of sugar. How many cups of coffee can he create from this?

• A. 1 cup of coffee
• B. 9 cups of coffee
• C. 2 cups of coffee
• D. 11 cups of coffee

Hint:

What is the limiting factor?

Answer 1

The Correct Option is A

Since each cup requires 1 teaspoon of coffee and 2 teaspoons of sugar, with 9 teaspoons of coffee and 2 teaspoons of sugar, Mr. Tokai can only make 1 cup of coffee. Hence, the correct answer is (a).
