Selling apples with out cost price at loss

Question

A vendor loses 4 apple price on selling 36 apples. What is his loss percentage?

I assume answer as 11.11% but answer was 10%. Am I thinking in reverse direction?

Answer 1

$$\text{The vendor loses 4 apple price on selling 36 apples}$$ $$\text{The vendor loses x apple price on selling 100 apples}$$

$$\frac{4}{x}=\frac{36}{100} \Rightarrow 36x=400 \Rightarrow x=11.11 $$

So, his loss percentage is $11.11 \%$.
