Question

X square + Y square upon x squared minus y square is equal to 17 upon 8 then what is the ratio of X:Y

Answer 1

Here given that

$\frac{x^2+y^2}{x^2-y^2}=\frac{17}{8}$

Cross multiplying

8 ( x² + y² ) = 17 ( x² - y²)

8x² + 8y² = 17x² - 17y²

17x² - 8x² = 17y² + 8y²

9x² = 25y²

$\frac{x^2}{y^2} = \frac{25}{9}\\\frac{x}{y} = \sqrt\frac{25}{9}\\\frac{x}{y}=\frac{5}{3}$

∴ x : y = 5 : 3
