RBC Assessment: Abstract Reasoning 2 — Questions and Answers
Question 1: A sequence shows: circle with 1 dot, square with 2 dots, triangle with 3 dots, circle with 4 dots. What comes next?
- Square with 5 dots (Correct answer)
- Triangle with 5 dots
- Circle with 5 dots
- Pentagon with 5 dots
Correct answer: Square with 5 dots
The shapes cycle circle→square→triangle and the dot count increases by 1 each step, so the next shape is a square with 5 dots.
Question 2: Each row contains three figures where the shading moves one position clockwise per step. If the top-left figure is shaded in position 1, where is the shading in the third figure of the same row?
- Position 1
- Position 2
- Position 3 (Correct answer)
- Position 4
Correct answer: Position 3
Moving clockwise one step per figure, position 1 → position 2 → position 3.
Question 3: In a 3×3 matrix, each row sums to 15 and each column sums to 15. The top row contains 6, 1, 8. The middle row contains 7, 5, 3. What is the missing value in the bottom-left cell if the bottom row is ?, 9, 2?
- 2
- 3
- 4 (Correct answer)
- 6
Correct answer: 4
The bottom row must sum to 15: ? + 9 + 2 = 15, so ? = 4.
Question 4: A pattern alternates between a large black shape and a small white shape of the same type. If the series begins: large black circle, small white circle, large black square... what is the 5th figure?
- Small white square
- Large black triangle (Correct answer)
- Small white triangle
- Large black circle
Correct answer: Large black triangle
Odd-numbered positions are large black shapes and the shape type advances: circle→square→triangle, making the 5th figure a large black triangle.
Question 5: Figures in a series gain one side per step: triangle (3), square (4), pentagon (5)... Which figure appears 4th?
- Pentagon
- Hexagon (Correct answer)
- Heptagon
- Octagon
Correct answer: Hexagon
Each step adds one side starting from 3, so the 4th figure has 3 + 3 = 6 sides — a hexagon.
Question 6: In an abstract matrix, the number of black dots doubles across each row: 1, 2, 4. The pattern repeats in each row but starts at the next whole number. The second row starts at 2. What is the last value in the second row?
- 4
- 6
- 8 (Correct answer)
- 16
Correct answer: 8
Starting at 2 and doubling twice gives 2, 4, 8, so the last value is 8.
Question 7: A set of shapes follows the rule: rotate 45° clockwise and add one interior line per step. The first shape is a square with 0 interior lines. How many interior lines does the third shape have?
- 1
- 2 (Correct answer)
- 3
- 4
Correct answer: 2
Each step adds one interior line, so after two steps (the third shape) there are 2 interior lines.
