Let the required number be x.

Therefore,

According to the given information:

$60\%\: of \: x +32 = x\\</p><p>\therefore \frac{60}{100} \times x + 32=x\\</p><p>\therefore 0.6x +32=x\\</p><p>\therefore 32=x - 0.6x\\</p><p>\therefore 32=0.4x\\</p><p>\implies x =\frac{32}{0.4}\\</p><p>\implies x =\frac{320}{4}\\</p><p>\implies x = 80$

Thus, the required numbers is 80.

Answer 2

The correct option is A) 80.

Step-by-step explanation:

Consider the provided information.

Let the number is x.

It is given that if we add 32 on 60% of x we will get the same number.

This can be written as:

60% of x + 32 = x

$\frac{60}{100}\times x + 32 = x$

$0.6x + 32 = x$

$x -0.6x =32$

$0.4x =32$

$x =\frac{32}{0.4}$

$x =80$

Hence, the required number is 80.

Therefore the correct option is A) 80.
