The purpose of non-verbal reasoning is to measure the reasoning power of candidates. In nonverbal reasoning, instead of words and numbers, diagrams are used for expressing ideas. You should carefully study the explanations and examples. Then you should do the practice test. The best method for increasing your speed and accuracy, is to do more and more practice tests within the allowed time. Non-verbal reasoning is classified into three groups. They are series, analogy, classification. Most of the questions are from series.
Basic Concepts :
Let us study how an element moves from one place to another. When it moves from 1 to 2, we say that the element moves ½ distance in ACW direction, similarly when it moves from 1 to 3, it is called 1 distance ACW direction. But when it moves from 1 to 8, we say that, the element moves ½ distance CW
direction. Similarly when it moves from 1 to 7, it is called 1 distance CW direction. If we are going to observe it on the basis of Degree, then it is to be followed as below:-
An element moves,
1 to 8 450 CW direction
1 to 7 900 CW direction
1 to 6 1350 CW direction
1 to 2 450 ACW direction
1 to 3 900 ACW direction and so on.
TYPE - 1
There should be two sets of figures in series section. The first one is question set, which consists of five figures. The second set is answer set. There are five figures and is numbered from 1 to 5. In the question set five figures are formed in a particular series you required . To find the answer figure from answer choices, which should be the sixth figure. At first you should observe whether there is any change in the shape or number of elements in the figures. Sometimes we can see that the elements in the figures move in a particular manner. Otherwise one of the elements will be replaced by a new one. In some cases both these changes occur at the same time.
Addition
The element moves diagonally and gets inverted in each step. Hence the answer is (2).
‘x’ moves clockwise. Hence figure (5) cannot be the answer. The element at the southeast corner in A is shifted to north-west corner in B. Then this element is replaced by a new one in C in the same position.
Then this new element is moved to southeast corner in D. Again this element is replaced by a new one in E in the same position. Finally, moved to the north- west corner (1). Hence the figures (2) and (3) can be ruled out. Similar treatment is done with the element at the south-west corner in A. Hence figure (1) continues the series.
Rotation
Watch the direction of rotation of element while observing the rotation of elements. They move either in clockwise direction or in anticlockwise direction. Then note, how much degree or by what distance they move. There are two types of rotation. In the first kind the element is stable while rotating. In the second is, the position of element changes while rotating.
Here the ‘L’ shape figure rotates 900 anticlockwise direction.There is the possibility for figure (3) or (5). Now consider the number of dots. The number of dots are same in A and B. Then one dot increased to obtain C. The dots remain same in C and D. Then one dot is increased to obtain E. So figure (5) is eliminated. Hence the answer is (3).
The element rotates 900 clockwise direction. So eliminate the figures (1), (3) and (4). The element is shifted to the next corner in CW direction in each step. So eliminate the figure (2). Hence answer is (5).
The cup shape element rotates 900 clockwise direction and moves 1 place in CW direction. The arrow moves diagonally. Therefore the answer is (4). In some cases the positions of elements interchange along with the change inelements.
