CLASS 9TH MENTAL ABILITY CHAPTER COMPLETION & FORMATION OF FIGURES

                                               FIGURE COMPLETION : 


     In such problems. A figure following a particular sequence or pattern is given. In which a part usually

     one-fourth is left blank. This problem figure is followed by four alternative figures. One is required to choose

     the one which best fit into the blank space of problem figure so as to complete the original pattern.

     Directions : (1 to 2) Select a figure from the four alternatives, which when placed in the blank space of figure (X) would complete the pattern. 

 

Ex.1    


    


Sol. Clearly, figure (D) will complete the pattern when placed in the blank space of figure (X) as shown below

 

Ex.2    


    


Sol. Clearly, figure (C) will complete the pattern when placed in the blank space of figure (X) as shown below.
       FIGURE FORMATION :
       Direction : (3 to 4) In the following question, find out which of the figure (A), (B), (C) and (D) can

       be formed from the pieces given in figure (X). 


Ex.3 


     


Sol. On close observation, we find that only figure (A) is combined figure (X).


        

 

Ex.4  


     


Sol. On close observation, we find that only figure (B) is combined figure of (X).
