1.	A convex lens is cut in half along its principal axis and the two halves are separated by a distance of 12 cm. An object is placed at a distance of 6 cm in front of one lens as shown in figure. Two sharp images are formed on the screen placed 80 cm from the object. The focal length of the lens (in cm),rounded to nearest ten is
