A convex lens, of focal length 30 cm, a concave lens of focal length 120 cm, and a plane mirror are arranged as shown. For an object kept at a distance of 60 cm from the convex lens, the final image, formed by the combination, is a real image, at a distance of :

Question

$\begin{array}{1 1}(1) \text{60 cm from the convex lens} \\ (2) \text{60 cm from the concave lens} \\(3) \text{70 cm from the convex lens} \\ (4)\text{ 70 cm from the concave lens} \end{array} $
