Directions to Solve

Each of the following questions consists of five figures marked A, B, C, D and E called the Problem Figures followed by five other figures marked 1, 2, 3, 4 and 5 called the Answer Figures. Select a figure from amongst the Answer Figures which will continue the same series as established by the five Problem Figures.

21.

Select a figure from amongst the Answer Figures which will continue the same series as established by the five Problem Figures.

Answer: Option
Explanation:
The symbols move in the sequence in the first step. In each subsequent step, the symbols move in the sequence obtained by rotating the previous sequence through 90oACW. Also, in each step, the symbol that reaches the encircled position gets replaced by a new one.

In each step, all the elements move to the adjacent corner (of the square boundary) in a CW direction and the element that reaches the upper-left corner gets vertically inverted.
23.

Select a figure from amongst the Answer Figures which will continue the same series as established by the five Problem Figures.

Explanation:
In each step, one line segment is lost from the CW-end of the outer element and a new line segment appears at the ACW-end. Also, the inner 'L' shaped element rotates 90oCW in each step.
24.

Select a figure from amongst the Answer Figures which will continue the same series as established by the five Problem Figures.

Answer: Option
Explanation:
In each step, the first element moves to the third position and gets replaced by a new element; the second and the third elements move to the first and the second positions respectively and the entire figure rotates 90oCW.
25.

Select a figure from amongst the Answer Figures which will continue the same series as established by the five Problem Figures.
