Answer : Concave mirror can produce both real image as well as virtual image . But according to the given condition the concave mirror is producing real and inverted image .We know that magnification , m = -v/u = hî/hô where, object distance = uimage distance = vGiven , u = -10cm and hî = 3hôSo, -v/u= 3hô/ô-v/u = 3v = -3uv = -3 × (-10)v = 30 cmHence, the image is 30 cm away from the concave mirror.Hope its help you.

Explanation of Image Formation by a Concave Mirror
- When an object is placed in front of a concave mirror, the mirror reflects the light rays and forms an image. The image can be either real or virtual, magnified or reduced, depending on the position of the object and the focal length of the mirror.

Given Information
- In this case, a concave mirror is producing a three times magnified real image of an object placed at 10 cm in front of it. This means that the height of the image is three times the height of the object.

Calculating the Position of the Image
- Using the magnification formula for concave mirrors, which is given by M = -v/u, where M is the magnification, v is the image distance, and u is the object distance, we can determine the position of the image.
- Given that the magnification is 3, and the object distance is 10 cm, we can substitute these values into the formula to find the image distance.
- Therefore, M = 3 = -v/10. Solving for v, we get v = -30 cm.

Location of the Image
- The negative sign indicates that the image formed is real and is located on the same side as the object. In this case, the image is formed at a distance of 30 cm from the mirror on the object's side.
- Therefore, the three times magnified real image of the object is located 30 cm in front of the concave mirror.
