Percentage Decrease

Percentage to Fraction Percentage to Decimal Percentage Increase Percentage Decrease

At times, while comparing two quantities, we also need to know the percentage decrease in value of given quantities. So the formula to find the percentage decrease is -

Percentage Decrease = (Decrease in value / Base Value) X 100

Let's study some examples to understand the percentage decrease

Example 1 : Julie reduced her weight from 80kg to 72kg in three months. Find percentage weight loss ?
Solution : Given things are
Original Weight : 80 kg
Current Weight : 72 kg

Now we will find the decrease in weight loss -
Decrease in weight = Original Weight - Current Weight
Decrease in weight = 80 - 72
Decrease in weight = 8 kg

Now we will apply the formula of percentage decrease and we get -

Percentage Decrease = (Decrease in value / Base Value) X 100
Percentage Decrease = (Decrease in Weight / Base Weight) X 100
Percentage Decrease = (8 / 80) X 100
Percentage Decrease = 0.10 X 100
Percentage Decrease = 10

So total percentage decrease in weight is 10 kg




Example 2 : Total sales reduced from 200 to 100. Find the percentage decrease in sales ?
Solution : Given things are -
Past total sales = 200
Current total sales = 100

Now we will find the decrease in sales -
Decrease in sales = Past Sales - Current Sales
Decrease in sales = 200 - 100
Decrease in sales = 100

Now we will apply the formula of percentage decrease and we get -

Percentage Decrease = (Decrease in Value / Base Value) X 100
Percentage Decrease = (Decrease in Sales / Past Total Sales) X 100
Percentage Decrease = (100 / 200) X 100
Percentage Decrease = 0.50 X 100
Percentage Decrease = 50%

So total percentage in decrease in sales is 50%
