Step-by-step explanation:

If we add 75 with 75% of that number

Thinking the number as x

(x × 75%) + 75=x

⇒(75x/100)+75=x

⇒75x/100=x-75

⇒x²=-75×100/75

⇒x²=-100

⇒x=-√100

⇒x=-10

Option 'c' is correct.

Step-by-step explanation:

Let the number be 'x'.

75% of that number becomes,

\dfrac{75}{100}x\\\\=\dfrac{3}{4}x\\\\=0.75x

On adding 75 with 0.75x , we get that number .

So, it becomes,

75+0.75x=x\\\\75=x-0.75x\\\\75=0.25x\\\\\dfrac{75}{0.25}=x\\\\300=x

Hence, Option 'c' is correct.
