Answer 2

Answer:

Decrease percentage of mobile is 25 %.

Step-by-step explanation:

Cost of a mobile in August = Rs 12,000

Cost of a mobile in October = Rs 9,000

Decrease in price of mobile = (Cost of a mobile in August) - (Cost of a mobile in October )

Decrease in price of mobile = Rs (12,000 - 9,000).

Decrease in price of mobile = Rs 3,000

Percentage decrease of mobile =

$( \frac{decease \: in \: price \: of \: mobile}{price \: of \: mobile \: in \: august} \times 100)\%$

$= ( \frac{3000}{12000} \times 100)\% \\ = ( \frac{1}{4} \times 100)\% \\ = 25\%$
