+226 It is difficult to work this out with the limited information. I have tried to relate it to a few common scenarios.
1) This question could be referring to 10,000.00 of a currency in a savings/bank account and asking how much interest would be earned on it at a rate of 10%?
2) This question could be referring to a debt of 10,000.00 of a currency on a loan/credit/charge card and asking how much interest would be charged on it at a rate of 10%?
Usually, rates of interest such as these are calculated per annum/year.
I will use the $ (dollar) sign for the currency to try to make it clearer as it's one of the most recognised currency symbols though this can easily be swapped for any other currency.
The calculations for this are the same;
You could start by determining what is 1% of $10,000.00
$${\frac{{\mathtt{10\,000}}}{{\mathtt{100}}}} = {\mathtt{100}}$$ So this shows that 1% of $10,000.00 is $100.00
Now we can easily find 10% 0f $10,000.00 by multiplying 1% ($100.00) by 10
$${\mathtt{100}}{\mathtt{\,\times\,}}{\mathtt{10}} = {\mathtt{1\,000}}$$ This shows that 10% of $10,000.00 is $1,000.00
In the case of example 1 above, this would mean that your $10,000.00 in your savings account would have increased by $1,000.00 to a total of $11,000.00
In the case of example 2 above, this would mean that your debt of $10,000.00 on your loan had increased by $1,000.00 to a total debt of $11,000.00
There are a few other ways you could calculate this;
$${\mathtt{10\,000}}{\mathtt{\,\times\,}}{\mathtt{0.1}} = {\mathtt{1\,000}}$$ The 0.1 being the decimal version of 10%, which gives the answer of $1,000.00, to be added to your original $10,000.00
$${\mathtt{10\,000}}{\mathtt{\,\times\,}}{\mathtt{1.1}} = {\mathtt{11\,000}}$$ The 1.1 being the decimal version of 110% which is the same as 100% (the original $10,000.00) plus the 10% (the $1,000.00) already added together for us. This being the quickest method as long as you can understand it.
If your calculator has a % button you could use this by typing $${\mathtt{10\,000}}{\mathtt{\,\times\,}}{\mathtt{10}}\% = {\mathtt{1\,000}}$$ to just find the interest or $${\mathtt{10\,000}}{\mathtt{\,\times\,}}{\mathtt{110}}\% = {\mathtt{11\,000}}$$ to find the interest with the original amount combined. I would not rely on this method though in case the calculator you were provided with for a test/exam didn't have this feature.
