Tailored for SSC CHSL Quantitative Aptitude. 3 active practice questions. Related topics: Percentage, Profit and Loss, Simple Interest.

SSC CHSL approach: For SSC CHSL, this topic should become a recognition-first skill. The main objective is to identify the standard pattern quickly and apply a clean, dependable method without overcomplicating the question.

What to master: Master direct forms first, then practise common variations until the opening step becomes automatic. Accuracy and quick recognition matter more than using advanced shortcuts.

SSC CHSL focus:

Prioritise clear fundamentals, quick recognition, and reliable execution for SSC CHSL objective questions.

Attempt strategy: For SSC CHSL, identify the standard pattern quickly, use the simplest valid method, and avoid spending extra time on unnecessary algebra or calculation.

Revision path: CHSL revision: basic rule -> standard pattern -> short timed drill -> accuracy check.

SSC CHSL exam emphasis for Statistics

CHSL emphasis: fundamentals, standard patterns, simple execution, and fast recall.

Most important error to avoid

Typical CHSL loss comes from hesitation, choosing a longer method than necessary, or forgetting the basic rule when the question is presented in a slightly different form.

Summary Formula Tricks Mistakes Solved Example Practice FAQ

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

SSC Statistics mainly uses descriptive measures such as mean, median and mode, together with simple interpretation of data. Choose the measure according to the question rather than using one formula everywhere.

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

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

Core concept
Key formula/relation
Common trap
Approved practice

Mean = Sum/Number
Median = middle observation after arranging data
Mode = most frequent observation

Always arrange ungrouped data before finding the median; frequency, not magnitude, determines the mode.

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: Find the mode of 2, 3, 3, 4, 5, 3 and 6.

Solution: The mode is 3.

In a Statistics practice set, a student answers 18 questions correctly out of 24. What percentage is correct?
Find the median of 2, 8, 5, 11, 7 and 14.
Find the mode of 4, 5, 5, 6, 7, 5 and 8.

Learn the shortcut first

Shortcut before you solve

Statistics becomes easier when you identify the required measure before calculating.

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

Identify the requested measure first: mean uses total/count, median uses ordered position, mode uses frequency.

Tip: Always arrange raw data before finding the median.

Step 1

Arrange the data: 1, 3, 5, 7, 9.

Step 2

The middle value is 5.

Rule

Median is the middle value after ordering; mean is sum divided by count.

3-second trick

Median: sort first. Mean: total first. Mode: count frequency.

Trap to avoid

Do not take the middle value from an unsorted list.

Correct answer

Thinking path

There are five observations.
The third value is central after sorting.
Therefore median = 5.

Final answer: 5

Why this is fast: Choosing the right statistical measure avoids unnecessary calculations.
