Answer 1

Answer:

put this formula Gain % = (Gain / CP) * 100. Loss % = (Loss / CP) * 100. SP = [(100 + Gain%) / 100] * CP

Step-by-step explanation:

Next, divide the increase by the original number and multiply the answer by 100: % increase = Increase ÷ Original Number × 100

To determine totals from a percent in the future, multiply the given percentage value by 100 and divide that product by the percent. This method works in any instance where a percentage and its value are given. For example, when 2 percent = 80, multiply 80 by 100 and divide by 2 to reach 4000.

Percentage increase is useful when you want to analyse how a value has changed with time. Although percentage increase is very similar to absolute increase, the former is more useful when comparing multiple data sets. For example, a change from 1 to 51 and from 50 to 100 both have an absolute change of 50, but the percentage increase for the first is 5000%, while for the second it is 100%, so the first change grew a lot more. This is why percentage increase is the most common way of measuring growth.
