When a real object is placed 25 cm from a lens, area image is formed. Mark the correct statement(s) 

For real object, real image can be formed by convex lens only (and not by concave lens) and depending on the location of object from $\infty$ to focus the image can be enlarged or diminished.When the object is in between f and 2f , image formed is real and enlarged , when the object distance is greater than 2f , the image formed is real and diminished . But when object is in between Focus and optical centre image would be virtual and enlarged . So $\mathrm{f}\le 25\mathrm{cm}$
