# A concave mirror produces three times magnified (enlarged) real image of an object placed at 10 cm in front of it. Where is the image located?

As the image is real , so the magnification(m) must be real.
$$m= \frac{h^`}h=\frac{-v}u = -3 or v=3u$$

$$u =-10cm$$

therefore, $$m= \frac{-v}u$$

$$-3= \frac{-v}{-10}$$

$$v= -30cm$$
