Most of the bank exam aspirants have an idea on quantitative aptitude topics, formulas, and shortcuts but the thing is to know where to use the shortcut and when to use makes difference. We become familiar with those tricks is only through practice.
At First know SBI PO Syllabus, Exam Pattern, and Cutoff Score. What kind of questions is asking? and how many questions are asking? With the analysis of SBI PO Previous years Question papers from Data Interpretation Part.
1) Missing values in a tabular form have given last time. The data will be given and some values have been missed we have to analyze the given data and find missing values.
The data in a paragraph will be explained and we need to answer the questions with the analysis of that paragraph.
2) Pie charts, Bar charts, Line charts
4) Mixed Graph: 1 pie chart along with a tabular data, 1 bar chart along with a tabular data.
5) Spider graph.
- Averages are nothing but additions and division of given numbers
- The ratio is nothing but comparing two same values in different niches.
- The percentage is nothing but finding some value out of 100.
Most Common questions are asking in this format from Percentages
1) x is what % of y that means x/y * 100.
2) what percentage is x of y? i.e. x/y * 100.
3) x is what percent more than y = x-y/y * 100
4) x is what percent less than y = y-x/y * 100
5) percentage change between two particular values = [final – initial/ initial] * 100
we need to memorize some fractional values and percentage values. click here for basic percentage values and fractional values to memorize for doing fast calculations.
