AFCAT Model Paper 1

The Logic here is as follows :
1. The symbols are moving in an anticlockwise direction.
2. Circles (shaded and blank) are moving in an anticlockwise direction.
3. The symbols x and + are moving as shown in the figures above.
The Correct series here is as follows: In the question, in figure 4, symbols '+' and 'x' are interchanged in order to get the correct answer.
In figure 4, + and x is moving in a clockwise direction. Thus, figure 4 does not fit into the series.
Hence, the correct answer is 'Option 4'.
