# 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 : $\frac{40}{100}\times 3500000$

= 500000 : 1400000 = 5 : 14
