Solves percentage change using \[p\%=\frac{Final \ - Initial}{Initial \space} \times 100\% \]
Percentage change quantifies the increase or decrease in a quantity over a given period. To calculate the percentage change, the formula is:
Percentage Change = [(New Value - Old Value) / Old Value] * 100
Initial= 50
Final value = 75
Percentage Change
[(75 - 50) / 50]* 100
[25 / 50]* 100
0.5 * 100
50%
In this example, the value increased by 50% from the old value of 50 to the new value of 75.
Old Value = 200
New Value = 150
Percentage of change
= [(150 - 200) / 200] * 100
= [-50 / 200] * 100
= -0.25 * 100
= -25%
In this example, the value decreased by 25% from the old value of 200 to the new value of 150.
Old Value = 80
New Value = 80
Percentage change
= [(80 - 80) / 80] 100
= [0 / 80] 10
= 0 * 100
= 0%
In this example, there is no change in value as the old value of 80 is the same as the new value of 80, resulting in a 0%.
