15% of 10000 is 1500—read that as £1500 on a £10000 base when you are thinking in pounds. Ten thousand is the classic “four zeros” anchor: 10% is 1000, and 5% is half of that, 500, so fifteen percent is a simple sum with no decimals. You can also halve and double: 15% of 5000 is 750, and 750 × 2 = 1500 because 10000 = 2 × 5000. Or count ten thousands: 15% of 1000 is 150, and 150 × 10 = 1500.
If the deal is 15% off 10000, the reduction is 1500 and you pay 8500 (£8500). That net total is what belongs in a final quote once the discount is applied.
The rest of the page keeps the method as 10% + 5% so you can check large figures in two steps you can say clearly. Compared with 15% of 5000, doubling the base doubles the fifteen-percent slice from 750 to 1500.
If £10000 is reduced by 15%, the reduction is £1500 and you pay £8500.

Formula used: (percentage ÷ 100) × number
Step 1: Take 10% of 10000: 1000.
Step 2: Take 5% of 10000 by halving 1000: 500.
Full formula: (15 ÷ 100) × 10000 = 1500
Add the parts: 1000 + 500 = 1500. There are 100 hundreds in 10000, and 15 × 100 = 1500 as a quick “per hundred” check. On the same ten-thousand total, 20% of 10000 is 2000—two tenths of the whole in one jump.
Moving the decimal for ten percent turns ten thousand into 1000 without fuss. Five percent halves that to 500, so fifteen percent is two round thousands-style chunks that add to fifteen hundred. That pattern is why many people rehearse large totals by stripping one zero for 10% before halving for 5%.
To see a much larger slice on the identical base, open 40% of 10000 alongside this page—the share jumps well past the fifteen-percent line.
