Accepted Answer

KEY CONCEPT :
When two plane mirrors are inclined a each other at an angle $	heta $ then the number of the images of a point object placed between the plane mirrors is
${{{{360}^ \circ }} \over 	heta } - 1,\,\,if{{{{360}^ \circ }} \over 	heta }$ is even
$	herefore$ Number of images formed
$ = {{{{360}^ \circ }} \over {{{60}^ \circ }}} - 1 = 5$
