Plant Operator Selection System Test Plant Operator Selection System Figural Reasoning 3 — Questions and Answers
Question 1: A sequence of figures shows: 1 small shape inside a large shape → 2 small shapes → 4 small shapes. How many small shapes appear in the next figure?
- 6
- 8 (Correct answer)
- 5
- 16
Correct answer: 8
The number of small shapes doubles each step: 1→2→4→8.
Question 2: A figure analogy: shaded pentagon is to unshaded pentagon as shaded hexagon is to ___.
- Shaded pentagon
- Unshaded hexagon (Correct answer)
- Shaded hexagon
- Unshaded pentagon
Correct answer: Unshaded hexagon
The relationship removes shading while keeping the shape, so shaded hexagon becomes unshaded hexagon.
Question 3: A 3×3 matrix has the numbers of sides of shapes increasing across each row (3,4,5) and increasing down each column. What shape belongs in the bottom-right cell if top-left is a triangle?
- Pentagon
- Hexagon
- Heptagon (Correct answer)
- Octagon
Correct answer: Heptagon
Row 3 starts at 5 sides in column 1, 6 in column 2, and 7 in column 3, giving a heptagon.
Question 4: Which figure does NOT belong in this group: equilateral triangle, isosceles triangle, right triangle, square?
- Equilateral triangle
- Isosceles triangle
- Right triangle
- Square (Correct answer)
Correct answer: Square
All triangles have three sides, while the square has four sides, making it the odd one out.
Question 5: A shape is reflected across a vertical axis. If the original shows a right-pointing arrow on the left side of a box, what does the reflection show?
- Right-pointing arrow on the right side
- Left-pointing arrow on the right side (Correct answer)
- Left-pointing arrow on the left side
- Right-pointing arrow on the left side
Correct answer: Left-pointing arrow on the right side
Reflection across a vertical axis flips left-to-right and reverses horizontal direction, moving the arrow to the right side and pointing left.
Question 6: A pattern shows figures where the inner shape is always the same type as the outer but smaller. If the outer shape is a circle and the inner shape is a square, which rule is violated?
- Size rule
- Shape-matching rule (Correct answer)
- Shading rule
- Position rule
Correct answer: Shape-matching rule
The rule states the inner shape should match the outer shape type, but a square inside a circle violates this shape-matching rule.
Question 7: In a folding problem, a flat cross-shaped net is folded into a 3D object. What shape does it form?
- Pyramid
- Cube (Correct answer)
- Cylinder
- Rectangular prism
Correct answer: Cube
A standard cross-shaped net with six equal squares folds into a cube.
A sequence of figures shows: 1 small shape inside a large shape → 2 small shapes → 4 small shapes.
