Percentages: concepts, worked examples and practice

Watch the complete 24-clip assembly supplied for this percentages lesson: meaning and fractions, percentage calculations, percentage increase, successive changes, percentage points, practice and recap. It is shared quantitative-foundation teaching, not the complete Government Exams & Civil Services syllabus or a separate examination-specific lesson for every programme.

Use these correct written steps alongside the video

The source footage is preserved. Some generated board graphics contain incorrect numbers, malformed equations, unrelated labels or UGC NET wording. In particular, do not copy the extra negative sign in the increase example or the stray algebra in the final practice questions. These written calculations are corrections, not a transcript of those graphics.

Meaning and percentage of a quantity

25% = 25 ÷ 100 = 1/4.

20% of 250 = (20 ÷ 100) × 250 = 50.

Alternatively, 10% of 250 = 25, so 20% = 2 × 25 = 50.

Finding a percentage

40 correct answers out of 50:

(40 ÷ 50) × 100 = 80%.

The denominator is the total number of questions, 50.

Percentage increase

250 − 200 = 50, not −50.

(50 ÷ 200) × 100 = 25%.

Divide the increase by the original value, 200.

Successive changes

100 × 1.20 = 120.

20% of 120 = 24; 120 − 24 = 96.

The net change is a 4% decrease, because the two changes use different bases.

Percentage points and relative increase

A rate changing from 40% to 50% increases by 10 percentage points.

Relative increase = (10 ÷ 40) × 100 = 25%.

These measure different things.

Practice answers

15% of 200 = (15 ÷ 100) × 200 = 30.

80 to 100: ((100 − 80) ÷ 80) × 100 = 25%.

10% discount on 500: 500 − 50 = 450.

AI-generated presenter and illustrative board visuals. All 24 ten-second source clips are included, with their original scene changes; this is not a single continuous camera take. The video does not establish affiliation with an examining body. Consult your selected programme’s published curriculum and reading material for examination-specific preparation.

Eight teaching scenes explain percentage increases, reference values and successive changes. Seven new admission scenes then show how to choose a programme, review its fee, enrol and start learning. This is a shared sample lesson with an admission invitation, not the complete syllabus or complete teaching video for any examination.

Online LMS learning support; the automated AI Course Tutor is not a promise of live personal tuition. An eligible trial covers one selected programme for 24 hours, with one trial per account. Paid access begins only after payment and access are confirmed.

AI-generated presenter and illustrative boards, not real student results or actual LMS screenshots. Fifteen source clips are assembled in order; the old “Next: Ratios” ending is replaced by the seven admission scenes. The original scene changes remain, so this is not a single camera take. A readable website and disclosure footer replaces malformed generated footers in the closing scenes. Consult your selected programme’s published lessons for examination-specific teaching.

Academic and professional-examination programmes provide learning support. The underlying degree, examination eligibility or professional qualification is governed by the relevant institution or examining body. Review the terms and refund policy before payment.
