This section appears only in IBPS PO Mains and is one of the most scoring yet time-consuming sections.

It does not test only calculation — it checks:

• Analytical thinking
• Data reading ability
• Mathematical application
• Decision-making speed
• Multi-concept clarity

Unlike Prelims DI, this section combines advanced arithmetic + logic + data comparison.

---

Core Data Interpretation Formats (Graph-Based)

These are traditional formats but asked at higher difficulty.

---

A. Tabular Data Interpretation

• Large data tables
• Missing values
• Percentage comparison
• Growth calculation
• Ratio comparison
• Conditional data filtering

Focus: Quick scanning + structured calculation.

---

B. Bar Graph (Simple & Clustered)

• Multiple bars comparison
• Year-wise growth
• Profit/Loss percentage
• Difference-based questions

Sometimes merged with:

• Line graph
• Pie chart

---

C. Line Graph

• Trend analysis
• Increase/decrease pattern
• Average growth rate
• Two-line comparison
• Combined data comparison

---

D. Pie Chart

• Market share
• Sector contribution
• Ratio transformation
• Value-to-percentage conversion
• Double pie chart combination

---

E. Mixed Graph DI

Combination of:

• Table + Pie
• Line + Bar
• Bar + Caselet

These require layered interpretation.

---

Caselet DI (Data in Paragraph Form)

No direct table given.

You must:

• Extract data from text
• Form table manually
• Solve arithmetic-based questions

Commonly based on:

• Sales data
• Production units
• Employee distribution
• Financial reports

This tests data structuring ability.

---

Missing Data Interpretation

• One or more values missing
• Solve equation to find missing value
• Based on averages, percentage or ratio

Requires algebraic thinking.

---

Data Sufficiency (Quantitative Type)

Given:

• A question
• Two or three statements

You must determine:

• Whether data is sufficient
• Whether both statements together are required

Concepts used:

• Percentage
• Ratio
• Time & Work
• Simple equations

Focus is logical elimination.

---

Quantity Comparison

Compare:

Quantity I vs Quantity II

Possible cases:

• Q1 > Q2
• Q2 > Q1
• Equal
• Cannot determine

Usually multi-step calculation required.

---

Advanced Arithmetic-Based DI

This is where difficulty increases.

DI may involve:

• Profit & Loss application
• Compound Interest
• Successive percentage change
• Time & Work with ratio
• Speed & Distance
• Mixture & Allegation
• Probability inside DI
• Partnership distribution

These questions combine concepts with data.

---

Ratio-Based DI

• Direct ratio conversion
• Inverse ratio problems
• Sharing and allocation
• Combined proportion logic

---

Percentage Change & Growth Analysis

• Year-on-year growth
• Successive percentage increase
• Decline & recovery rate
• CAGR (basic concept)

Often used in financial datasets.

---

Data Comparison & Ranking

• Rank sectors based on output
• Identify maximum/minimum growth
• Identify inconsistent trend
• Compare average across categories

Tests interpretation rather than calculation.

---

Probability-Based DI

Occasionally integrated.

• Selection probability from given data
• Arrangement probability
• Conditional probability using dataset

---

Data Interpretation with Logical Condition

• Conditional filtering
• Constraint-based selection
• If–Then cases
• Group elimination

This mixes reasoning + DI.
