Four percentage sums people need most
- What is 15% of 8,000? Multiply 8,000 × 0.15 = 1,200
- 1,200 is what percent of 8,000? Divide 1,200 ÷ 8,000 × 100 = 15%
- Change from 8,000 to 9,200? (9,200 − 8,000) ÷ 8,000 × 100 = 15% increase
- Add 15% to 8,000? 8,000 × 1.15 = 9,200
Why up and down are not equal
If a price rises 20% and then falls 20%, it does not come back to where it started. Rs 1,000 becomes Rs 1,200, then 20% off Rs 1,200 is Rs 960. Always calculate the percentage on the number you are starting from.
Percentage points or percent?
If a bank rate moves from 10% to 12%, it has risen by 2 percentage points, but by 20% of the old rate. News reports sometimes mix the two, so check which one is meant.
