What is 20% of 300?
The answer is 60.
Why Sixty on Three Hundred
Three hundred is 3 × 100, so twenty percent scales as three times the one-hundred row—ideal for quick benchmarking against “per hundred” thinking.
Against 20% of 150 (30): doubling the base from one-fifty to three hundred doubles the fifth (30 × 2 = 60).
Mental Maths Shortcuts for 20% of 300
Fastest: 300 ÷ 5 = 60.
- 10% of 300 = 30; double → 20% = 60.
- 3 × (20% of 100) → 3 × 20 = 60.
From 25% of 300 = 75, subtract 5% of 300 = 15 to land on sixty—useful if quarters come first mentally.
Real-World Examples
Example 1: Twenty percent off a £300 fee
The markdown is £60 and you pay £240 if nothing else stacks.
Example 2: Three-hundred-unit batch
If a 20% quality hold applies, 60 units are ring-fenced and 240 are free to ship under a strict rule.
Example 3: Budget line
Allocating 20% of a £300 sub-budget means £60 for that line and £240 notionally elsewhere—not the other way round unless the wording says “after discount.”
Example 4: Tenfold check
20% of 3000 is 600. If you see 60 or 6000 on the scaled row, revisit the percent-to-decimal step.
Common Mistakes
- Answering £240 when asked only for twenty percent of £300—two hundred and forty is after the discount.
- Multiplying 20 × 300 without dividing by a hundred → 6000.
- Confusing 20% of 300 with “300 is 20% of what?” (300 ÷ 0.2 = 1500).
- Using 300 ÷ 20 as a percentage trick—it is not the fifth.
- Treating 0.2% of three hundred as twenty percent.
