### focal length = f = - 15 cm object distance = u = -25 cmimage distance = v = ?hi = ?ho =  4 cm Mirror formula,1/v + 1/u = 1/f Thus, to get image of object sharp it has to be placed at 37.5 cmSize of image is 6 cmAs the height of object is more and negative, nature of image is real, inverted and magnified.
