A fruit seller had some apples. He sells 40% of those apples and still has 240 apples. How many apples did he originally have?

Correct option is A

Given:
The fruit seller sells 40% of his apples.
After selling 40%, he still has 240 apples.
Solution:

Let the original number of apples be "x".
After selling 40% of the apples, 60% of the apples are left. Therefore, the remaining apples are 60% of x.
Remaining apples = 0.6x
We know that remaining apples = 240, so:
0.6x = 240
x = $$\frac{240} {0.6}$$​​
x = 400
Therefore, the fruit seller originally had 400 apples.
