Question:
Assume that patterns such as Pattern A and Pattern B are distinct. How many patterns appear in the Figure 1?
Assume that patterns such as Pattern A and Pattern B are distinct. How many patterns appear in the Figure 1?
Show Hint
In visual perception questions, always start by counting the obviously distinct patterns. If your count is lower than the options, re-examine the image for subtle variations in line weight, spacing, or pattern density, as these are common tricks.

The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
The task is to count the number of unique patterns present in the 8x8 grid. The problem specifies that rotated patterns are considered distinct (e.g., vertical stripes are different from horizontal stripes). We must carefully scan the grid and identify every unique design.
Step 2: Key Formula or Approach:
The approach is to systematically categorize and list each pattern found in the grid, ensuring no duplicates are counted. We can group patterns by type (e.g., solid, striped, geometric shapes) to maintain a clear count.
Step 3: Detailed Explanation:
Let's list the unique patterns by scanning the grid row by row.
Clearly Distinguishable Patterns:
Solid Fills: 1. White square 2. Black square
Geometric Shapes: 3. Black circle 4. Black diamond 5. Central black dot
Bordered Patterns: 6. White square with a full border
Corner Patterns (4 distinct rotations): 7. Black corner (top-left) 8. Black corner (top-right) 9. Black corner (bottom-left) 10. Black corner (bottom-right)
Single Line Patterns (2 distinct rotations): 11. Single diagonal line (/) 12. Single diagonal line (\textbackslash)
Grid/Checkerboard Patterns: 13. Crosshatch (thin grid lines) 14. 2x2 checkerboard 15. Dithered pattern (fine 4x4 or 8x8 checkerboard)
Striped Patterns:
16. Three vertical bars
17. Three horizontal bars
18. Diagonal stripes (
)
19. Diagonal stripes (//)
Step 4: Final Answer:
By identifying all clearly distinct patterns, we find 19.

- A bank needs to upgrade its ATM kiosks to be wheel-chair accessible. An ATM kiosk entrance has four steps rising up to reach the floor level of the kiosk. Each step is 1000 mm in length, 300 mm in breadth, and 150 mm in height. The bank proposes to create a wheel-chair accessible ramp with a slope of 1:12, adjacent to the steps. What is the minimum horizontal length of the ramp in metre? \
