Given that a bakery sells boxes of muffins where ratio of apple to blueberry muffins in each box is the same.
So that means ratio of numbers given in column 2 and column 3 of the table will always be same.
Let's use 2nd and 5th row and use x for the missing value to make an equation, we get:
x/15=40/50
multiply both side by 15
x=(40/50)*15
x=12
Similarly we can make ratio of other rows with 5th row to find missing values.
You will get values as shown in attached picture of the table.
