RBC Assessment: Abstract Reasoning 5 — Questions and Answers
Question 1: A sequence of figures shows: figure 1 has 2 black and 0 white dots; figure 2 has 2 black and 1 white dot; figure 3 has 2 black and 2 white dots. What does figure 5 look like?
- 2 black and 3 white dots
- 2 black and 4 white dots (Correct answer)
- 3 black and 4 white dots
- 4 black and 4 white dots
Correct answer: 2 black and 4 white dots
Black dots stay constant at 2 while white dots increase by 1 per step; figure 5 has 2 black and 4 white dots.
Question 2: An abstract matrix has the rule: the middle cell value equals the sum of the four corner cells divided by 2. Corner values are 4, 6, 2, and 8. What is the center value?
- 8
- 10 (Correct answer)
- 12
- 16
Correct answer: 10
(4 + 6 + 2 + 8) / 2 = 20 / 2 = 10.
Question 3: A pattern codes letters as shapes: A=circle, B=square, C=triangle, D=diamond. The sequence of shapes is: circle, triangle, square, diamond, circle. What letter sequence does this represent?
- ABCDA
- ACBDA (Correct answer)
- ACBDA
- ABDC A
Correct answer: ACBDA
Circle=A, triangle=C, square=B, diamond=D, circle=A → ACBDA.
Question 4: In a figure series, lines are added inside a shape to form diagonals. A square with 0 diagonals is step 1; step 2 has 1 diagonal; step 3 has 2 diagonals. The rule changes at step 4: no more diagonals are added but the shape gains one side. What is step 5?
- Pentagon with 2 diagonals
- Hexagon with 2 diagonals (Correct answer)
- Hexagon with 3 diagonals
- Pentagon with 3 diagonals
Correct answer: Hexagon with 2 diagonals
Step 4 is a pentagon with 2 diagonals; step 5 adds another side giving a hexagon, still with 2 diagonals.
Question 5: A figure transformation applies: (1) reflect vertically, (2) rotate 180°. Applied in sequence to an arrow pointing up-right, what is the final direction?
- Up-right (Correct answer)
- Down-right
- Up-left
- Down-left
Correct answer: Up-right
Reflecting vertically changes up-right to down-right; rotating 180° then brings it back to up-right.
Question 6: A 3×3 matrix contains the numbers 1–9 each exactly once. Each row and column sums to 15. The top row is 2, 7, 6 and the middle row is 9, 5, 1. What is the bottom-left cell value?
- 3
- 4 (Correct answer)
- 6
- 8
Correct answer: 4
Bottom row must contain 3, 4, 8 to use remaining numbers and sum to 15; the leftmost column has 2 and 9 (sum=11), needing 4 to reach 15.
Question 7: An odd-one-out question: five shapes are shown — a red circle, a blue circle, a red square, a blue triangle, and a blue square. Which shape is the odd one out?
- Red circle
- Blue circle
- Red square
- Blue triangle (Correct answer)
Correct answer: Blue triangle
The blue triangle is the only shape that does not have a matching counterpart in the other color (there is no red triangle).
