A point object O is placed at a distance...

A point object O is placed at a distance of 60 cm from a concave mirror of radius of curvature 80 cm.
(a) At what distance from the concave mirror should a plane mirror be kept so that rays converge at O itself after getting reflected from the concave mirror and then from the plane mirror?
(b) Will the position of the point where the rays meet change if they are first reflected from the plane mirror?
