These questions are mostly oriented toward logical conclusion and quick calculation rather than remember big formulas (as in case of other chapters of quantitative aptitude subject). Students are given raw data (in form of Line Graphs, Table, Pie Charts in quantitative aptitude), or series of numbers (for missing numbers problems), a couple of equations (in Data sufficiency problems) and asked to conclude required inferences after visualizing data points.
