What is the value of x, if 25% of 480 + 30% of 500 + x% of 90 = 35% of 900 ?

50

According to question ,

25% of 480 + 30% of 500 + x% of 90 = 35% of 900

\(\frac{1}{4}\) × 480 + \(\frac{3}{10}\) × 500 + \(\frac{x}{100}\) × 90 = \(\frac{35}{100}\) × 900

120 + 150 + \(\frac{9x}{10}\) = \(\frac{7}{20}\) × 900

120 + 150 + \(\frac{9x}{10}\) = \(\frac{7}{20}\) × 900

270 + \(\frac{9x}{10}\) = 315

x = 50
