Let's say is "x", so, then "x" is the 100%, and we know that the 60% is 120, what the dickens is "x" anyway?

\bf \begin{array}{ccll}
marks&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
x&100\\
120&60
\end{array}\implies \cfrac{x}{120}=\cfrac{100}{60}\implies x=\cfrac{120\cdot 100}{60}

tiny-mole [99]

Answer:

Jane can fill 6364 cases with the remaining 6364 bottles.

Step-by-step explanation:

Total number of bottles Jane need to put = 8500 bottles.

Till the given time she put 2136 bottles.

Number of bottles left =  Total number of bottles she need to put - total number of bottles she put till that time

Number of bottles left  = 8500 - 2136

 Number of bottles left  = 6364 bottles.

Number of cases left must be equal to number of bottles left

So, Jane can fill 6364 cases with the remaining bottles.

Thus, Jane can fill 6364 cases with the remaining 6364 bottles.
