Question:-

If 50 is subtracted from two-third of a number, the result is equal to sum of 40 and one-fourth of that number. What is the number?

S O L U T I O N :-

Let number be $x$

$\rm{\dfrac{2x}{3} - 50 = \dfrac{x}{4} + 40}$

can be written as

$\rm{\dfrac{2x}{3} - \dfrac{x}{4} = 50 + 40}$

$\sf{\dfrac{8x - 3x}{12} = 90}$

$\sf{\dfrac{5x}{12} = 90}$

$\rm{x = \dfrac{90 × 12}{5}}$

$\bf \implies \color{blue}{216}$
