The correct answer is:
$\quad P$ virtual and upright real and inverted
Focal length of convex lens $=20 \mathrm{~cm}$
Here, object $P$ is at $10 \mathrm{~cm}$
and object $Q$ is at $30 \mathrm{~cm}$.
As object $P$ is between focus and pole, it's image is virtual and erect.
Object $Q$ is beyond focus, so it's image is real and inverted.
