Before we go through the main problem, we have to take an example that will help to do the main problem. Let suppose we are buying $25$ apple at $Rs.125$ then we have to find the cost of $1$ apple.

So, we are buying $25$ apple at $Rs.125$that means $1$ apple is cost is $\Rightarrow \dfrac{125}{25}=Rs.5$.

Now we will take another example of it. Let suppose the cost of $60$ oranges are $Rs.360$ . Now we

Have to find how many oranges we will get in $Rs.120$ .So, for this case, we see that the cost of $1$

Orange is $=\dfrac{360}{60}=Rs.6$ .So, we get $\dfrac{120}{6}=20$ oranges in $Rs.120$ .

Now we go through our given problem,

It is given that $15$ liters of refined oil cost $Rs.1063.30$.

So, we need to find the cost of 1-liter refined oil that will be $\dfrac{1063.30}{15.5}=68.60$

Thus we get that $1$ liter refined oil cost $Rs.68.60$.
