CET Test Taking Strategies
Visual Reasoning
Presented By: Dwijendra B. Srivastava
Visuals are very important
OVERVIEW The Myths:
•
Additional skills are required to solve a visual reasoning question.
•
Despite a lot of practice, we cannot solve most of visual reasoning questions.
•
There is no fixed approach or formula for solving visual reasoning questions.
•
A visual reasoning question looks complex so it will be difficult to solve.
•
It takes more time to solve VR questions than other questions.
Different types of questions:
1
Odd man out

Non geometric figure
Example:
HINT: Pick any two figure say ‘c’ and ‘d’ we observe only figure that contains arrow their logic of movement is different so out of ‘c’ and ‘d’ one is our required answer. Comparing movement of elements of ‘c’ and ‘b’ we get their logic to be different. Hence ‘c’ is the required answer.

2. Analogy In Analogy based Visual Reasoning the question types are: (They should be answered in the foll. order of priority:)
• Four figures based analogy question • Five figures based odd one out. • Options figures that are either similar or dissimilar to question figure. (Four options are either similar or dissimilar to question figure and one is different)
Example:
? (i)
1] HINT:
(ii)
2]
(iii)
3]
(iv)
4]
5]
Here we trace movement of elements from (ii) to (i) as we need to get fig (iii) from fig (iv). In first figure ‘ ’ exchanges its position with ‘ ’ so ‘1’ should exchange it’s position with ‘A’. Hence except ‘3’ and ‘4’ all other options get eliminated. Again observing movement of element ‘5’ we can easily get option ‘4’ as answer.
While solving analogy question you should first pick:
• • •
Four-figures analogy Odd one from five figures The option is similar or dissimilar to the question figure
3. Series theVisual givenreasoning series the question types are: InComplete Series based
• •
Complete the series of five figures
•
Interchange a pair of figure in the sequence to get a correct series.
•
Spot the error in seven figures where first and last figures are correct
C. N. R. Rao
Odd one Out figure in the series
Approaches to tackle the Series Based Visuals: If you see many elements in a VR question, don't get tensed. • Count the total number of each number of elements in one figure
element or total
• Try to find out the relation between these numbers in the following figures. • Sometime only some elements in each figure bear a relation in the corresponding figures. • This whole process will take less than a minute.

The question figure may seem to be cluttered with a lot of figures, but we can easily observe here that sum of numbers of arrows and circles is constant. Hence (4)
If counting doesn't work, pick any one element from the figure and try to trace its movement. The transformations that the element can go through are:
• • • •
Clockwise or anticlockwise direction movement Half a space or full space movement Lateral inversion (mirror image) or Vertical inversion (Water image) A combination of these movements

While solving the series question always keep in mind to solve each question in less then a minute and order for prioritizing the questions of the series questions should be:
• •
seven figure series first, then odd one in the series,
•
the questions that require interchanging figures to complete the series.
followed by the five figure complete the series question and lastly,

Types of question that should be least priortized. Although the figure seems simple these questions shoule be avoided as the elements are similar and it’s difficult to trace the movement of an element. Examples:
