Summary Formula Tricks Mistakes Solved Example Practice FAQ

Data Interpretation revision for SSC MTS: understand the base rule, apply the correct formula or relation, check common traps, then practise with approved questions.

Data Interpretation tests arithmetic applied to tables, charts and sets of values. Read the units and base first, then decide whether the question needs difference, ratio, average or percentage change.

SSC MTS focus: Solve the core method first, then use the approved practice questions on this page to build exam-speed accuracy.

Data Interpretation revision rule: concept → formula/relation → one worked example → timed practice → error review.

Core concept
Key formula/relation
Common trap
Approved practice

% change = (New-Old)/Old × 100
Average = Total/Number
Ratio a:b = a/b

Do not calculate every value in a chart. Read the question first and extract only the required cells.

Read the exact requirement before choosing a shortcut.
Keep units, signs and percentage bases consistent.
Use the final few seconds to verify direction and magnitude.

Using a memorised shortcut without checking its condition.
Skipping unit or base conversion.
Doing long arithmetic before identifying the underlying relation.

Practice example: In a Data Interpretation practice set, a student answers 18 questions correctly out of 24. What percentage is correct?

Solution: Correct percentage = 18/24 x 100 = 75%.

Learn the shortcut first

Shortcut before you solve

Data Interpretation is faster when data extraction and calculation are kept separate.

Faster solving steps

Use this 4-step method before solving to keep your thinking fast and repeatable.

Step 1 Identify relation

Spot the pattern, relationship, or core idea first.

Step 2 Apply same pattern

Use the same rule instead of re-solving from scratch.

Step 3 Eliminate wrong options

Remove confusing choices before comparing the last few.

Step 4 Confirm final answer

Pick the option that matches the shortcut most cleanly.

Now apply the trick on real questions

Use the shortcut above before solving these questions

Read labels and units first, then extract only the values required by the question.

Tip: Do not calculate every value in the chart; identify the exact rows, columns and comparison needed.

Step 1

Increase = 250 - 200 = 50.

Step 2

Percentage increase = 50 / 200 x 100 = 25%.

Rule

Use the correct original or reference value as the base for percentage, ratio or difference.

3-second trick

Mark the exact values needed before calculating.

Trap to avoid

Do not use the final value as the percentage base for an increase.

Correct answer

25%

Thinking path

Original value is 200.
Increase is 50.
The percentage increase uses the original value as base.

Final answer: 25%

Why this is fast: Ignoring irrelevant chart values reduces calculation and error.
