Question

A fruit seller had some apples. He sells $40$% apples and still has $420$ apples. Originally, he had:

• A. $588$ apples
• B. $600$ apples
• C. $672$ apples
• D. $700$ apples

Answer 1

The correct option is D $700$ apples

Suppose originally he had $x$ apples
Then, $(100-40)$% of $x=420$
$\Rightarrow$ $\frac{60}{100}\times x=420$
$\Rightarrow$ $x=\left(\frac{420\times 100}{60}\right)=700$
