Mixed Diagrams (DI)

Mixed Graph Questions in DI 

Combination of two (or sometimes more) types of data representation, which are :

  • Pie Chart and Data Table
  • Data Table and Line Graph
  • Bar Graph and Line Graph
  • Pie Chart and Line Graph
  • Pie Chart and Pie Chart

Important Points : 

  • Sometimes, only one form of data representation may not be adequate to fully describe all the facets of the situation.
  • In such cases, where the desired parameter may be a function of two or three variables, the data may be presented as a combination of two or more forms of data presentation.
  • Identify the kind of data being presented in each format and establish a functional relationship between the various formats. We look for the common parameter that connects the different formats.
  • At times, when one graph gives the data of different categories or years, the other graph might give more details about a single category or year.
  • More skillful Interpretation is required, since one needs to analyze two or more graphs at a time. 
  • Suitable for complex, practical situations where there are multiple facets for each situation. 

 

Example : 

Study the following graph and table carefully and answer the questions given below it.

Question : 

What is the percentage of candidates qualified from states 'A' and 'C' together of the total candidates appeared? 

Solution : 

Number of Candidates qualified from States A and C together
= 49/100 x 15/100 x 300000 + 61/100 x 18/100 x 300000
= 22050 + 32940 = 54990
Required percentage = 54990/300000 x 100 = 18.33%

 Example : 

Bar-graph shows number of candidates appeared (in lakh) in different years and line graph shows percentage of candidate qualified in examination over the years.

Question: 

What was the ratio between number of candidates appeared in 2009 to Number of candidates qualified in 2016?

Solution: 

Required Ratio = 500000 : 40100×3500000 

= 500000 : 1400000 = 5 : 14
