Question

iii) Find the value of x and y
in x: y= 2 : 5 and 4: x = 3 : 8​

Answer 1

Step-by-step explanation:

$\frac{4}{x } = \frac{3}{8} \\ x = \frac{32}{3}.............(1) \\ now \: \frac{x}{y} = \frac{2}{5} \\ y = \frac{5}{2} \times x \\ y = \frac{5}{2} \times \frac{32}{3} \\ y = \frac{80}{3} \\so \: answer \: x = \frac{32}{3} \\ y = \frac{80}{3}$
