NNAT3 Serial Reasoning 3 — Questions and Answers
Question 1: A matrix has three rows. Each row's shapes increase in number: row 1 has 1 star, row 2 has 2 stars, row 3 has ___.
- 3 stars (Correct answer)
- 4 stars
- 1 star
- 2 stars
Correct answer: 3 stars
Each row adds one star, so row 3 contains 3 stars.
Question 2: In a pattern sequence, shapes get lighter in shade each step: black, dark gray, gray, ___. What comes next?
- Light gray (Correct answer)
- White
- Black
- Dark gray
Correct answer: Light gray
The shading decreases one level per step, making the next shade light gray.
Question 3: A 3×3 grid contains X, O, and △ in each row, each appearing exactly once. Row 1 is X-O-△, row 2 is O-△-X. What is row 3?
- △-X-O (Correct answer)
- X-O-△
- O-X-△
- △-O-X
Correct answer: △-X-O
Each symbol shifts one position left each row in a Latin square pattern, giving △-X-O for row 3.
Question 4: A serial pattern shows a rectangle, then the same rectangle with a diagonal line, then the rectangle with two diagonal lines. What comes fourth?
- Rectangle with three diagonal lines (Correct answer)
- Plain rectangle
- Rectangle with one diagonal line
- Rectangle with four diagonal lines
Correct answer: Rectangle with three diagonal lines
One diagonal line is added per step, so the fourth figure has three diagonal lines.
Question 5: Each row of a matrix has shapes that grow larger left to right: small-medium-large. The pattern in columns is ___.
- The same size appears in each column across all rows (Correct answer)
- Sizes are random in columns
- Columns alternate sizes
- Each column shrinks top to bottom
Correct answer: The same size appears in each column across all rows
In a consistent size matrix, the same size (e.g., small) appears in the same column across all rows.
Question 6: A sequence shows: circle inside a square, circle inside a triangle, circle inside a pentagon, ___. What is the missing figure?
- Circle inside a hexagon (Correct answer)
- Square inside a circle
- Circle inside a square
- Circle inside a triangle
Correct answer: Circle inside a hexagon
The outer shape gains one side each step (4→3→5 is irregular; correcting: square=4, pentagon=5, hexagon=6).
Question 7: In a 3×3 matrix, each row has one black cell and two white cells. Moving down, the black cell shifts from position 1 to position 2 to position ___.
- Position 3 (Correct answer)
- Position 1
- Position 2
- No black cell
Correct answer: Position 3
The black cell moves one position to the right each row, reaching position 3 in the third row.
A matrix has three rows.
Each row's shapes increase in number: row 1 has 1 star, row 2 has 2 stars, row 3 has ___.
