A coat was $20 it was reduced to $ 15.
By how much percentage did it reduce.
Provide step by step solution

Answer 1

Answer:

The Decrease% is 25%.

Step-by-step explanation:

Given :

The Cost of the coat = $ 20

It was reduced to = $ 15

To Find :

The Decrease %

Solution :

Original Value = 20

Change in Value = 20 - 15

★ We Know That :

$\boxed{\mathsf{Decrease \: \% = \left[\dfrac{Change \: in \: Value}{Original \: Value}\right]\times 100}}$

$\sf{\implies} \: Decrease \: \% = \left[ \dfrac{20 - 15}{50}\right] \times 100$

$\sf{\implies} \: Decrease \: \% = \dfrac{5}{20} \times 100$

$\sf{\implies} \: Decrease \: \% = \dfrac{500}{20}$

$\sf{\implies} \: Decrease \: \% = 25$

$\purple{\sf{\implies} \: Decrease \: \% = 25\%}$

$\therefore$ The Decrease% is 25%.

Answer 2

Decrease = Decrease ÷ Original Number × 100

==> 20-15/20 × 100

==> 5 ÷ 20 × 100

==> 0.25 × 100

==> 25 %

Decrease % = 25%
