Question

A fruit seller had some apples. He sells 40% apples and still has 420 apples. How many apples did he have originally ?

Answer 1

% of apples sold = 40%
% of apples left = 60%

Number of apples left = 420
$\mathrm{Percentage}\mathrm{formula}:\frac{\mathrm{Part}}{\mathrm{Whole}}=\frac{\mathrm{Percent}}{100}\mathrm{Therefore},\mathrm{Whole}=\frac{\mathrm{Part}\times 100}{\mathrm{Percent}}\Rightarrow \mathrm{Total}\mathrm{apples}=\frac{420\times 100}{60}=700$
