## How to Calculate Decrease Percentage?

To calculate Decrease Percentage, we need to find out the difference between the two numbers which we are comparing. The formula used is** Decrease Percentage = Original number – New number.**

After subtracting, we will divide the decrease by the original number, and then we will multiply the answer by 100. And if we need to find the % Decrease, we will use formula,

**% Decrease = Decreased Value / Original number × 100**

By this method, you can calculate the % Decrease. Below you can see some solved examples on Decrease percentage.

1. Find out the Decrease Percentage of the given below:

(i) 45 by 9%

(ii) 60 by 12%

(iii) 125 by 25%

## Solution:

(i) 45 by 9%

The given value is 45 by 9%,

As the number 45 was decreased by 9%,

So, first, we will find the new number,

As a new number= 45 – decreased percentage,

which means

= 45 – (9% ×45)

on solving we will get 40.95.

So, the decreased percentage is 40.95.

(ii) 60 by 20%

The given value is 60 by 20%,

As the number 60 was decreased by 20%,

So, first, we will find the new number,

As a new number= 60 – decreased percentage,

which means

= 60 – (20% ×60)

on solving we will get 48.

So, the decreased percentage is 48.

(iii) 125 by 60%

The given value is 125 by 60%,

As the number 125 was decreased by 60%,

So, first, we will find the new number,

As a new number= 125 – decreased percentage,

which means

= 125 – (60% ×125)

on solving we will get 50.

So, the decreased percentage is 50.

2. Solve out the number when decreased by:

(i) 16% becomes 480

(ii) 3% becomes 194

(iii) 35% becomes 1950

## Solution:

(i) 16% becomes 480

Here, we should find out the number,

So let the number be X

as given 16% was decreased,

So, decreased number= X – (16% × X), on solving we will get

= 0.84X

given that the number which when increased by 16% becomes 480, which means

0.84X =480, on solving we will get

X = 571 approx.

(ii) 3% becomes 194

Here, we should find out the number,

So let the number be X

as given 3% was decreased,

So, decreased number= X – (3% × X), on solving we will get

= 0.97X

given that the number which when increased by 3% becomes 194, which means

0.97X =194, on solving we will get

X = 200.

(iii) 35% becomes 1950

Here, we should find out the number,

So let the number be X

as given 35% was decreased,

So, decreased number= X – (35% × X), on solving we will get

= 0.65X

given that the number which when increased by 35% becomes 1950, which means

0.65X =1950, on solving we will get

X = 3000.

3. The classroom strength of the girls was decreased by 24 from 60. What is the decrease percentage?

## Solution:

First, we will find the decreased number 60 – 24= 36,

then we will find the % of the decrease by using the formula

%Decrease = Decrease / original number × 100

= 36/60 ×100

on solving, we will get 60%

So, the decrease percentage is 60%.

4. The TV price was $2500 in the year 2019. And it was reduced to $1500 in 2020. What percent did the price of the TV reduced?

## Solution:

In 2019 the TV price is $2500,

and in the year 2020, the price was reduced to $1500

The reduced price of the TV is $2500- $1500=

on solving we will get $1,000,

now, we will find the % of the decrease by using the formula

%Decrease = Decrease / original number × 100,

= 1000/ 2500 × 100

on solving, we will get

= 40%.

So the percent of the TV reduced is 40%.

5. A bike company was advertised a brand new model bike sale for $1,20,000 and was sold for $1,00,000. What was the percent reduced?

## Solution:

The advertised price of the bike is $1,20,000,

it was sold for $1,00,000

the reduced price of the bike is $1,20,000- $1,00,000=

on solving we will get $20,000.

now, we will find the % of the decrease by using the formula

%Decrease = Decrease / original number × 100,

= 20,000/1,20,000 × 100

on solving, we will get

= 16.67%.

So the percent of the bike reduced is 16.67%.
