Solution

Let's denote the original number as x.

According to the problem, 75% of x (which is 0.75x) added to 75 equals the original number x.

So, we can write the equation as follows:

0.75x + 75 = x

To solve for x, we can start by subtracting 0.75x from both sides of the equation to isolate x on one side:

75 = x - 0.75x

This simplifies to:

75 = 0.25x

Then, to solve for x, we divide both sides of the equation by 0.25:

x = 75 / 0.25

x = 300

So, the original number is 300. Therefore, the answer is (B) 300.
