The correct option is C 12:5tape diagram: The above tape diagram shows the ratio between Joe, Robert and Robert, Alex respectively. From the above tape diagram, if Robert has 4 rectangles then Alex will have 5. Since the earnings of Joe and Robert are in the ratio 3:1, Joe will have 3×4=12 rectangles which is shown in tape diagram below. Thus, the ratio between Joe and Alex is 12:5.
