Question

if a price of a shirt decreased from rs. 80 to rs. 60, find the percentage decrease.

Answer 1

Decrease = Rs 80 - Rs 60 = Rs 20
Percentage decrease = (Decreased amount / Original amount) *  100
           = 20 / 80  * 100  = 25 %
 

Answer 2

Answer:

$Decrease\: percentage =25\%$

Step-by-step explanation:

Original price of the shirt = Rs 80

After decrease price of shirt = Rs 60

Decrease amount (d)= Original price - decreased price

= Rs 80 - Rs 60

= Rs 20

$Decrease\: percentage=\frac{d}{Original\:price} \times 100\\=\frac{20}{80}\times 100\\=25\%$

Therefore,

$Decrease\: percentage =25\%$
