Answer 1

There is a mistake in 4040%

Answer 2

Answer:

The actual number is either 1 or 0.

Step-by-step explanation:

Let the actual number be x.

40% of x is

$\text{40\% of x}=\frac{40}{100}x$

It is given that 40% of a number when added to square of same number than it is increased to 40% of itself.

$\frac{40}{100}x+x^2=\frac{140}{100}x$

$x^2-x=0$

$x(x-1)=0$

Equate each factor equal to 0.

$x=0,-1$

Therefore the actual number is either 1 or 0.
