# A man purchased 20 litre of oil.He gave 5*3/4 litre of oil to his son and 6*1/5 litre to her daughter.Find the oil left with him.

Given a man purchased 20 liter of oil

And

Gives $5\frac{3}{4}$ liter of oil to his son and $6\frac{1}{5}$ liter of oil to his daughter .

So, oil left with him = $20-5\frac{3}{4}-6\frac{1}{5}=20-\frac{20+3}{4}-\frac{30+1}{5}=20-\frac{23}{4}-\frac{31}{5}=\frac{400-115-124}{20}=\frac{161}{20}=\mathbf{8}\mathbf{.}\mathbf{05}\mathbf{}\mathit{l}\mathit{i}\mathit{t}\mathit{e}\mathit{r}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{(}\mathbf{\hspace{0.17em}}\mathit{A}\mathit{n}\mathit{s}\mathbf{}\mathbf{)}$
