Abstract Reasoning Logical Deduction 2

Question 1

In an odd-one-out question: circle, oval, ellipse, square. Which is the odd one out?

Accepted Answer

Square

Answer

Circle, oval, and ellipse all have curved edges with no corners; a square has four corners, making it the odd one out.

Question 2

A code in an abstract test maps shapes to numbers: triangle=3, square=4, pentagon=5. What does hexagon equal?

Accepted Answer

6

Answer

The code maps each shape to its number of sides; a hexagon has 6 sides, so hexagon = 6.

Question 3

In a classification question: which shape does NOT belong with the others — equilateral triangle, isosceles triangle, right triangle, square?

Accepted Answer

Square

Answer

All triangles have three sides; a square has four sides and does not belong in the group of triangles.

Question 4

If shape A implies shape B, and shape B implies shape C, and shape C is absent, what can you conclude?

Accepted Answer

Shape A is absent

Answer

By the contrapositive: if C is absent (¬C), then B is absent (¬B), then A is absent (¬A).

Question 5

An abstract test shows: all large shapes have thick borders, some thick-bordered shapes are triangles. Shape R is a large triangle. What can be deduced?

Accepted Answer

Shape R has a thick border

Answer

The first rule states all large shapes have thick borders; Shape R is large, so it must have a thick border.
