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

Exam-Specific Tips

  • Mixed DI typically contributes 5 questions worth 10 marks in SSC CGL Tier-II
  • Bar Chart + Line Graph combination appears in 60% of mixed DI questions
  • Questions involving percentage calculations comprise 40% of mixed DI problems
  • Ratio and proportion questions account for 25% of mixed DI question types
  • Time period analysis questions appear in 80% of mixed DI sets
  • Average calculation questions feature in 30% of mixed DI problem sets
  • Unit conversion errors cause 35% of wrong answers in mixed DI sections
