In this type of test there are two sets of figures, first set is called problem figures and the second set is called answer/option figures. In the problem figure set the figures always form some type of pattern. These figures may be rotating clockwise or anti-clock wise or changing there shape or size but in a fixed pattern.
Once the pattern or relation between the problem figures is understood then the next figures can be easily picked out of answer figure set.

Lines emerging from the circle are decreasing by one line each figure. In fourth figure, six lines are emerging so answer figure is figure C with five lines.
