Answer 1

Hey mate..
=========

Let, the number be x

Given,

75% of a number is added to 75 to get the same number.

i. e. $75\% \times x + 75 = x$

=> $\frac{75x}{100} + 75 = x \\ \\ = > 0.75x - x = - 75 \\ \\ = > - 0.25x = - 75 \\ \\=> x = \frac{ - 75}{ - 0.25} \\ \\ = > x = \frac{75 \times 100}{25} \\ \\ = > x = 300$

The required number is 300

Hope it helps!!
