Explanation:

Height of object = +6 cm

Object distance = -50 cm

Focal length = +30 cm

Lens formula = 1/f = 1/v - 1/u

                       1/v = 1/f + 1/u

                       1/v = 1/30 - 1/50

                             = 5-3/150

                             = 2/150

                       Image distance = 150/2 = +75.5 cm

                          height of image  =  image distance

                           height of object       object distance

                             h =  75.5 x 6

                                        - 50

                               h = +9.06 cm

      Hence image formed is virtual, erect, and magnified

Hope it helps!!H!
