What does it require to master D.I.?
D.I. requires calculations after taking out the relevant figures from the charts. One has to be quick in arithmetic and statistics. Most problems entail the comparison of numbers.
The most important key to solve D.I. is filtering out the useful information from the large body of data presented. In this step, we identify the data that is required to answer the question, without being confused by the rest. For instance a table of sales data may give figures for 10 years. But if the question requires calculating the growth rate of a particular year, then we need only to look at the relevant figures for those years.
D.I. requires a good practice of dealing in numbers, viz. percentages i.e. 37.5 is what % of 70, 20 amounts to 33.3% in a total of how much, what is % increase etc. Knowledge of multiplication tables, squares, cubes etc. reduces calculation time drastically.
