A convex lens of focal length $\displaystyle 20$ cm produces images of the same magnification $\displaystyle 2$ when an object is kept at two distances $\displaystyle x_1$ and $\displaystyle x_2\left(x_1>x_2\right)$ from the lens. The ratio of $\displaystyle x_1$ and $\displaystyle x_2$ is :
Official answer
(3)
$\displaystyle 3$ : $\displaystyle 1$
