ELEN [110]

Answer:

Total 495 liters of natural oil are needed.

Explanation:

It is given that Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains 5 liters of natural oil for every 3 liters of synthetic oil.

It means the ratio of natural oil and synthetic oil is

\frac{\text{Natural oil}}{\text{Petrolyn motor oil}}=\frac{5}{5+3}=\frac{5}{8}

Let in order to make 792 liters of Petrolyn oil he needs x liters of natural oil.

It means the ratio of natural oil and synthetic oil is

\frac{\text{Natural oil}}{\text{Petrolyn motor oil}}=\frac{x}{792}

Equate both ratios,

\frac{x}{792}=\frac{5}{8}

On cross multiplication we get

8\times x=5\times 792

8x=3960

Divide both sides by 8.

x=\frac{3960}{8}

x=495

Therefore total 495 liters of natural oil are needed.
