If $\frac{x+y}{x-y} = \frac{7}{3}$, then $x:y$ is equal to / यदि $\frac{x+y}{x-y} = \frac{7}{3}$ है, तो $x:y$ बराबर है

$2:5$
2.
$5:2$
3.
$7:3$
4.
$3:7$
Correct Answer: $5:2$
Cross-multiplying, $3(x + y) = 7(x - y)$, so $3x + 3y = 7x - 7y$; hence $4x = 10y$ and $x:y = 10:4 = 5:2$. / तिर्यक गुणा से $3(x + y) = 7(x - y)$, अतः $4x = 10y$ और $x:y = 5:2$।
