40% of 300= 120.

Step-by-step explanation:

Let's the number is 100u (u denotes unit)

Then, 75% of the number is= (75%×100u)=75u

According to question if 75 is added to 75% of the number then it will be (75u+75) and it will be equal to the number itself.

So, 100u=75u+75

Or, 25u=75

Or, 1u=3

then 100u=300

The number is 300
