UCAT Abstract Reasoning 3

Question 1

In an odd-one-out question, four shapes are squares and one is a rhombus with unequal diagonals. Which is the odd one out?

Accepted Answer

Rhombus with unequal diagonals

Answer

The rhombus with unequal diagonals is not a square, making it the odd one out.

Question 2

A pattern rule states: the total number of sides across all shapes in each box remains constant at 12. A box has one square (4 sides) and one pentagon (5 sides). What shape completes the box?

Accepted Answer

Triangle

Answer

4 + 5 = 9 sides used; 12 − 9 = 3 sides needed, so a triangle completes the box.

Question 3

Each row in an abstract reasoning question has shapes that increase in shading from 0% to 50% to 100%. The third shape in a row where the first is 0% shaded and the second is 50% shaded is:

Accepted Answer

100% shaded

Answer

The pattern increases shading by 50% each step: 0% → 50% → 100%.

Question 4

Set A figures all have internal symmetry (at least one line of symmetry). Set B figures have no lines of symmetry. Which set does a regular pentagon belong to?

Accepted Answer

Set A

Answer

A regular pentagon has 5 lines of symmetry, so it belongs to Set A.

Question 5

In a series, each figure is produced by connecting every third dot on a circle: 12 dots → 4-pointed star, 15 dots → 5-pointed star, 18 dots → ?

Accepted Answer

6-pointed star

Answer

With 18 dots and connecting every third, 18/3 = 6 points, producing a 6-pointed star.
