UPSC CAPF – 2015
– **Group 1: (1, 7, 8)**
– Figure 1: Triangle, single internal line.
– Figure 7: Triangle, multiple radial internal lines from a vertex/near center.
– Figure 8: Circle, multiple radial internal lines from the center.
– One possible classification criterion for this group could be: “Figures which are either a triangle with an internal line originating from a vertex, or a circle with radial lines from the center.” (1 and 7 are triangles with lines from vertex/near center; 8 is a circle with lines from center).
– **Group 2: (4, 5, 6)**
– Figure 4: Triangle, two crossing internal lines dividing into 4 regions.
– Figure 5: Circle, two crossing internal lines dividing into 4 regions.
– Figure 6: Square, two crossing internal lines dividing into 4 regions.
– A clear classification criterion for this group is: “Figures that are divided into four regions by two crossing internal lines.” All figures in Group 2 fit this criterion.
– **Group 3: (2, 3, 9)**
– Figure 2: Circle, single internal line (diameter).
– Figure 3: Square, single internal line (through center).
– Figure 9: Square, multiple radial internal lines from the center.
– One possible classification criterion for this group could be: “Figures which are either a circle with a single line passing through the center, or a square with internal lines passing through or originating from the center.” (2 is a circle with a line through the center; 3 is a square with a line through the center; 9 is a square with lines from the center).
