If the plane mirrors are not inclined to each other and if they are parallel, then infinite number of images are formed.

Let the mirrors be M1 and M2.  1st images of I1 and I2 of the candle C in M1 and M2 will be at 20 cm behind M1 and M2 respectively.   

Image due to I1 in M2,  and due to I2 in M1 will be at 60 cm behind the mirrors respectvely.

Then the next images will form 100 cm behind the mirrors.   It will continue for ever like that.

We will have infinite number of images formed on both sides of mirror. The distance between the mirrors is not relevant in this case; will only govern the distances of the images formed, not the number images.
