Three of the following four figures are alike in a certain way and one is different. Select the odd one.

Mistake PointsIt may seem that option 3 can be the answer also because it has 5 circle head lines whereas others have 4 circle head lines. But then what is the purpose of giving polygon figures here which are different in all options.

In the three given figures, the number of the lines above the shapes is the same as the number of the sides of the shape below.

There are five sides in the shape in the above image, but there are only four lines at the top of the shape.

Hence, option figure (1)  is different from the three images given in the option.

Alternate MethodFigure 1- The number of circle head lines above the shape is 4 and the sides of the shape are 5

Figure 2- The number of circle head lines above the shape is 4 and the sides of the shape are 4

Figure 3- The number of circle head lines above the shape is 5 and the sides of the shape are 5

Figure 4- The number of circle head lines above the shape is 4 and the sides of the shape are 4

Figure 1 is different from others.

Hence, Figure 1 is the correct answer.
