Percentage increase/decrease calculation

The percentage increase/decrease from old value (Vold) to new value (Vnew) is equal to the old and new values difference divided by the old value times 100%:

percentage increase/decrease = (Vnew - Vold) / Vold × 100%

Example #1

Price percentage increase from old value of $1000 to new value of $1200 is caluclated by:

percentage increase = ($1200 - $1000) / $1000 × 100%

 = 0.2 × 100% = 20%

Example #2

Price percentage decrease from old value of $1000 to new value of $800 is caluclated by:

percentage decrease = ($800 - $1000) / $1000 × 100%

 = -0.2 × 100% = -20%

Difference and final value calculation

The difference d is equal to the initial value V0 times the percentage increase/decrease p divided by 100:

d = V0 × p / 100

The final value V1 is equal to the initial value V0 plus the difference d:

V1 = V0 + d

What is the consequence of changing over the condition? Completing every one of the changes recorded above can give either a condition that has indistinguishable roots from the first condition, or a condition, among the underlying foundations of which contains every one of the foundations of the first condition, however which can likewise have different roots, or a condition that does exclude every one of the roots underlying foundations of the changed condition. In the accompanying passages, we will dissect which of these changes under which conditions lead to which conditions. It is critical to know for the fruitful arrangement of conditions.
