Detailed Solution

The number of images of an object placed in between them will be

11 .

The number of images (N) can be calculated by using the following formula:

N = \frac{(360)}{x} - 1 - - - (1)

where x is the angle of inclination.
On substituting the values in the equation (1), we get
⇒

N = \frac{(360)}{12} - 1

⇒

N = 12 - 1

⇒

N = 11

Hence, the number of images of the object will be

11 .
