Question 1: In a pattern, each square is shaded one additional quadrant clockwise per step. After 4 steps, how many quadrants are shaded?
- 1
- 2
- 3
- 4 (Correct answer)
Correct answer: 4
Starting unshaded, after 4 steps all 4 quadrants are shaded.
Question 2: Two identical shapes overlap. The overlap region has 4 square units; each shape is 10 square units. What is the combined visible area?
- 16 (Correct answer)
- 20
- 24
- 18
Correct answer: 16
Total visible area = 10 + 10 − 4 = 16 square units.
Question 3: A grid pattern has a dot moving one cell right and one cell down each step. If it starts at position (1,1), where is it after 3 steps?
- (3,3)
- (4,4) (Correct answer)
- (2,4)
- (4,3)
Correct answer: (4,4)
Starting at (1,1) and moving +1,+1 each step: (2,2), (3,3), (4,4) after 3 steps.

- 1/6
- 1/2
Correct answer: 1/3
6 − 4 = 2 unshaded triangles; 2/6 = 1/3 of the hexagon is unshaded.
