A)
for converging lens
focal length f is positive
using lens equation
1/f = 1/do + 1/di
do is the object distance = 12 cm
f = 30 cm
1/f = 1/do + 1/di
1/30 = (1/12)+(1/di)
1/di = (1/30)-(1/12)
di = -20 cm
di = 20 cm
negative sign indicates the image is on the same side of the object
B) magnification is m = -di/do = hi/ho
20/12 = hi/1
hi = 1.67 m
an upright image and on the same side of the object the image is formed
