Data Interpretation — formula, example and practice

Tables and bar graphs. Approximate first, then exact only if options are close.

Content type: original worked example. Not labelled as a previous-year question.

Timed GK/quant mock Shortcuts CBSE Class 10 Maths 150 questions

Formula

Read the unit on the axis first. Percentage of a total = (part/total)×100

Tables, bar, line and pie. Arithmetic you already know, applied to printed data.

What you should learn here

Pie 360° = 100%. One percent is 3.6°. Banking DI is heavier than SSC GD; start with one table a day.

Worked example

Question. If a bar shows 40 against a total of 200, what percent is it?

Solution. 20%.

Common mistake. Ignoring “in thousands” in the footnote and treating 15 as 15 instead of 15,000.

When to use the shortcut. Estimate first. Compute exactly only when two options are close.

FAQs

Are these previous-year SSC questions?

No year or shift is claimed on these pages. Each maths section has 150 original practice MCQs. When a verified source database exists, a question will show exam + year; until then it is practice.

Where are Class 10 board formulas?

The CBSE formula sheet at /cbse/class-10/mathematics/formulas/ stays the canonical board list. This maths hub links to it instead of copying every line.

Do you publish tricks that are only sometimes true?

Every shortcut page states when the trick must not be used. A speed trick that fails on close options is not published as if it were a theorem.
