This page covers SSC MTS Mixed DI (2-graph sets) with complete concept notes, 21 graded practice MCQs, key points and exam-specific tips. Free to study.
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 Patterns
What 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.

Shortcuts
Use these to save 30–60 seconds per question
🔑Scan Method
Quickly scan both graphs to understand the relationship between them before reading questions

⚡Unit Conversion Trick
When graphs have different units (thousands vs lakhs), convert to same unit immediately to avoid calculation errors
✏️
Worked Example
Solve 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%
Convert to required unit = 18 thousand cars
Answer: 18,000 cars or 18 thousand cars
Common Mistakes: 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.
