Question

A biconvex lens of focal length f 1 = 10 cm is placed 40 cm in front of a concave mirror of focal length f 2 = 7.50 cm , as shown in the figure. An object, 2 cm high, is placed 20 cm to the left of the lens. The image formed by the lens, as rays travel to the right, is, Real and erect, Virtual and erect, Real and inverted, Virtual and inverted
