This post will guide you through different types of questions on Pie Chart in DI section you might face in your entrance examination.
Introduction to Pie-chart:
Pie Charts represent the total of certain values, which may be the source of profit for an organization, the total sales of a product with each of the organizations having a share in the total sales number for the year, distribution of certain value into the variables that these are composed of. It is taken as a circle with angle at the centre being 360 degrees. The distribution of the factors that are being considered gives these a share in the total. This is the percentage share in the total and also denotes the angle which it forms at the centre out of 360 degrees. A set of questions in DI section of Bank exams, CAT, XAT, IIFT may be asked; in case of SBI PO exam one of the questions may have a pie-chart rather than a set of questions based on pie-charts and data.

- Another question that can be asked is about the questions for the ones time was allocated but could not be solved. Also, there could be questions on the ones that were solved but were incorrect.
Strategy for solving
- Questions on pie-charts are not like the ones on bar charts and line graphs. Questions on pie charts are not asked that frequently.
- The kind of skills required to solve these are similar to the ones required for solving questions with data being represented on a stacked bar chart.
- Solving does not require more than a minute. The calculations can get you an approximate figure. A five digit number can be reduced to a two digit number by approximation. A value that helps you reach the correct alternative can be found through approximation.
