What is Non Verbal Reasoning?
Non verbal reasoning is a figure based reasoning. It has no language at all. To solve nonverbal problems one has to find out the pattern of pictorial presentation in the given figure. To get more clear concept about non verbal reasoning, let us see the types of problems coming before you.
Types of Problems
(a) Problems Based on Mirror Image
In a mirror image, left part of an object becomes right part and right part becomes left part. Remember the rule given below.
Left Hand Side (L.H.S.) \[\underset{{}}{\leftrightarrows}\] Right Hand Side (R.H.S.)

(iii) 

(iv) 
Explanation:
(i) Actual Figure:
Mirror Image:
Clearly, L.H.S. becomes R.H.S. and R.H.S. becomes L.H.S.
(ii) Actual Figure:
Mirror Image:
Clearly, L.H.S. becomes R.H.S. and R.H.S. becomes L.H.S.
(iii) Actual Figure:
Mirror Image:
In this case, the actual figure and its mirror image both will be same because there is no difference in the L.H.S. and the R.H.S. sides of the figure. Hence, in actual sense, the L.H.S. does become the R.H.S. and the R.H.S. does become the L.H.S., but this change does not appear to you. Therefore, remember the following rule.
Rule X = If "L.H.S. = R.H.S', then mirror image and the actual figure will be similar
(iv) Actual Figure:
Mirror Image:
Clearly, L.H.S. becomes R.H.S. and R.H.S. becomes L.H.S.

Explanation:

\[\therefore \] Actual figure and Mirror image are same.
(iii) Actual Figure:

Clearly, L.H.S. becomes R.H.S. and R.H.S. becomes L.H.S.
(iv) Actual Figure:
Mirror Image:
Here,
L.H.S. = R.H.S. (See Rule X)
\[\therefore \] Actual figure and Mirror image will be similar.
(v) Actual Figure::

(b) Problems Based on Water Image.
In water image, the actual figure gets inverted vertically. In other words, in water image top becomes bottom and bottom becomes top but there is no change in LH.S. and R.H.S. like mirror image. LH.S. remains L.H.S. and R.H.S. remains R.H.S.
Remember the rule given below.
Example 1: Actual figure Water Image 

(i) 

(ii) 

(iii) 

(iv) 
Explanation:
Clearly, top becomes bottom and bottom becomes top.
Clearly, top becomes bottom and bottom becomes top.
In this case, the actual figure and its water image both will be same because there is no difference in the top and the bottom parts of the actual figure. Therefore, in actual sense, the top does become the bottom and the bottom does become the top, but this change does not appear to you. Therefore, remember the following rule:
Clearly, top becomes bottom and bottom becomes top.

Explanation:
Clearly, top becomes bottom and bottom becomes top.
Clearly, top becomes bottom and bottom becomes top.
Here, Top = Bottom (See Rule: Y)
\[\therefore \] Actual figure and water images will be similar.
Clearly, top becomes bottom and bottom becomes top.
Here, Top = Bottom (See Rule: Y)
\[\therefore \] Actual figure and water image will be similar.

(c) Problems Based on Geometrical Shapes
Geometrical shapes come from geometry which is the math of shapes made of points and lines. Some shapes are simple such as a triangle, square and circle, whereas other shapes are complex. While solving reasoning based on geometrical shapes, following points are important:
Rotation: Turning of any figure around a point is called rotation.
(i) Two half rotations mean one full rotation.
(ii) Rotation means figure rotates \[90{}^\circ \] clockwise or \[90{}^\circ \] anticlockwise.
(iii) Rotation means figure rotates \[45{}^\circ \] clockwise or \[45{}^\circ \] anticlockwise.
Counting Geometrical Shapes: In order to count the geometrical shapes, we identify the shapes and solids by their names and images.
Embedded Figures: If a figure contains another figure as its parts, the figure part is called embedded figure.
1. For a cube,how many cubes are there in the figure given below?
(a) 44 (b) 48
(c) 46 (d) 52
(e) None of these
Answer: (a)
Explanation: Number of cubes in first layer = 14
Number of cubes in second layer = 14
Number of cubes in third layer = 8
Number of cubes in fourth layer = 4
Number of cubes in fifth layer = 4
Total number of cubes \[=14+14+8+4+4=44\]

Answer (b)
Explanation: Number of cubes in first layer = 7
Number of cubes in second layer = 5
Number of cubes in third layer = 4
Number of cubes in fourth layer = 3
Number of cubes in fifth layer = 3
Total number of cubes \[=7+5+4+3+3=22\]

Commonly Asked Question
(a) (b)
(c) (d)
(e) None of these
Answer: (d)
Explanation: Option (d) is correct because it is vertically inverted figure of the actual figure. Let us see:
Clearly, top of the actual figure becomes the bottom of option (d) and the bottom of the actual figure becomes the top of the option (d).
Rest of the options is incorrect because of the correctness of option (d).
