Solves percentage addition using \[c=a-b \% \times \frac{a}{100} \]
Percentage subtraction is a mathematical operation that involves subtracting a certain percentage from a given value. This process allows us to calculate the difference resulting from the reduction of a certain percentage from a whole.
%subtraction = a - b% * a/100
Where a is the original value, b is the amount in percentage subtracted from a
Let's subtract 15% from 200.
Calculation
200 - (15/100 * 200) = 200 - 30 = 170
The difference after subtracting 15% from 200 is 170.
Subtract 25% from 800.
Solution
800 - (25/100 * 800) = 800 - 200 = 600
The difference after subtracting 25% from 800 is 600.
Subtract 10% from 1500.
Solution
1500 - (10/100 * 1500) = 1500 - 150 = 1350
The difference after subtracting 10% from 1500 is 1350.
Subtract 5% from 50.
Calculation: 50 - (5/100 * 50) = 50 - 2.5 = 47.5
The difference after subtracting 5% from 50 is 47.5.
