Data interpretation is the most scoring and time-consuming section in IBPS and other competitive examinations. In quantitative aptitude section, you can see at least 2 data interpretation sets each having 5 questions. In PO level there are 40-50 questions in Quantitative aptitude section and the sectional cutoff remains 18-19. So if you solve those two sets corrected you need to solve 10 questions out of remaining 40 questions. Here are three important techniques to make Data Interpretation calculations fast
◆Visual Estimation
It is a well-known fact that it is near to impossible to solve 200 questions in 120 minutes accurately. The term "Accurately" is important here because I have seen many candidates attempting 190+ questions and fails to qualify. The reason behind the failure is low accuracy and many times accuracy level falls below 40%. An important point to be noted down here is by attempting 190+ with low accuracy you get less time for questions you are sure about and there is negative marking in most of the competitive exams.
Now lets come to our topic. How to use visual estimation technique to solve Data Interpretation questions. Let's take a visual example:-(consult picture)
Example - Red bars states wheat production state and Green bars states rice production.
Question - In which year percentage increase Wheat production was highest?
As you can see there is an increase of 5 tonnes in production both wheat and rice production every year.
10% of 50 = 5
10% of 70 = 7
So the answer should 2006.
