Answer 1

Question :-

10% of x° is the compliment of 40% of 2x.

Find x ?


Answer :-

$\dfrac{10}{100} \times x = 90 - \dfrac{40}{100} \times 2x$


$\dfrac{x}{10} = 90 - \dfrac{8x}{10}$


$\dfrac{x}{10} + \dfrac{8x}{10} = 90$


$\dfrac{9x}{10} = 90$


$9x = 900$


$x = \dfrac{900}{9}$


$x = 100$
