A fruit seller had some apples. He sells 40% apples and still has 420 apples. Originally, he had:
588 apples
600 apples
672 apples
700 apples
Explanation:
Suppose originally he had x apples.
Then, (100 - 40)% of x = 420.
$\dfrac{60}{100}x x = 420 $
=>x = $\dfrac{420 x 100}{60}$ = 700.
Suppose originally he had x apples.
Then, (100 - 40)% of x = 420.
$\dfrac{60}{100}x x = 420 $
=>x = $\dfrac{420 x 100}{60}$ = 700.
