Q164
ReasoningAnalogy, Classification & Odd One Out
Find the odd one out:
  1. a.Square
  2. b.Circle
  3. c.Parallelogram
  4. d.Rectangle

Answer: (B) Circle

Square, rectangle and parallelogram are quadrilaterals - closed figures bounded by four straight sides with four angles - while a circle is a curved figure with no sides or corners. In fact every square is a rectangle and every rectangle is a parallelogram, which makes the three a family and the circle the odd one out.
