Answer 1

\(x-\left[\frac{50x}{100}+\frac{25x}{200}\right]=11\frac{1}{4}\)

\(x-\left[\frac{50x\cdot2}{200}+\frac{25x}{200}\right]=11\frac{1}{4}\)

\(x-\left[\frac{100x}{200}+\frac{25x}{200}\right]=11\frac{1}{4}\)

\(x-\frac{125x}{200}=11\frac{1}{4}\)

\(\frac{200x}{200}-\frac{125x}{200}=11\frac{1}{4}\)

\(\frac{200x-125x}{200}=11\frac{1}{4}\)

\(\frac{75x}{200}=11\frac{1}{4}\)

\(\frac{3x}{8}=11\frac{1}{4}\)

\(3x=11\frac{1}{4}\cdot8\)

\(3x=90\)

\(x=30\)

Vậy x = 30
