Concept Notes

Mixed DI (2-graph sets)— Rules & Concept

Core ConceptRead this first — the foundation of the topic

Core Concept

Mixed DI tests your ability to extract information from multiple visual formats and combine them to solve complex problems. Questions often require data from both graphs to reach the answer

Key Rules

Always read both graph titles and legends carefully. Identify what each axis represents. Note the units and scales used. Check if data represents absolute numbers, percentages, or ratios.

Look for common elements between both graphs like time periods, categories, or subjects.

Exam PatternsWhat examiners ask — read before attempting PYQs

SSC CGL typically asks 5 questions per set. Common question types include percentage calculations across graphs, ratio comparisons, finding averages, calculating differences, and trend analysis. Questions may ask for data from one graph only, but often require combining information from both.

ShortcutsUse these to save 30–60 seconds per question

Scan Method

Quickly scan both graphs to understand the relationship between them before reading questions 2

Unit Conversion Trick

When graphs have different units (thousands vs lakhs), convert to same unit immediately to avoid calculation errors

Worked ExampleSolve this step-by-step before moving on

1

Step 1

Extract production data for 2019 from Bar Chart = 60 thousand cars

2

Step 2

Extract export percentage for 2019 from Line Graph = 30%

3

Step 3

Calculate exported cars = 60,000 × 30/100 = 18,000 cars

4

Step 4

Convert to required unit = 18 thousand cars Answer: 18,000 cars or 18 thousand cars

Exam TrapsCommon mistakes students make — avoid these

Students often use data from wrong years, mix up absolute numbers with percentages, forget unit conversions, or use data from only one graph when both are required. Another frequent error is misreading scales or legends, especially when graphs use different scales. Time Management: Spend 30 seconds understanding both graphs, then 90 seconds per question. Don't get stuck on complex calculations - use approximation when answer choices are far apart.

Key Points to Remember

Mixed DI combines two different graph types with related data themes
Always identify the relationship between both graphs before attempting questions
Check units and scales carefully - graphs may use different measurement units
Most questions require data from both graphs, not just one
Convert percentages to absolute numbers using: (Percentage × Total)/100
Read graph legends and axis labels completely to avoid misinterpretation
Use approximation when answer choices have significant gaps between them
Allocate 8-9 minutes total for 5 questions in mixed DI sets
