Detailed Solution

It is given that Kristian is making bread using the recipe. She observes that her sister consumed the majority of the sugar syrup for her breakfast and now she is left with

16

cup of syrup.
We know that if two quantities

x

and

y

vary in the same way while maintaining a constant ratio between their respective values, then the two quantities are said to be in direct proportion.
i.e.

x y = k,

where k is a constant positive number.
If one ingredient is reduced in quantity for a perfect bread recipe, the other ingredients must also be reduced proportionately.
Let’s assume the quantity of ingredients decreased is represented by variables as shown in below table.
