Using the lens formula; -1/u+1/v=1/f

rearranging, 1/v=1/18-1/27=1/54

hence 1/v=1/54.

To get the position of the image, V, find the reciprocal of 1/54.

Hence, v=54cm.

To obtain the size and nature of image,

use magnifcation formula; hi=V/u*h=54/-27*4=-8.0cm.

Therefore, size of image is 8cm.

Nature=virtual image.
