Let the original price of the article be x.

According to Question,

(100-20)% of x = 300

=> 80/100 x = 300

=> x = 375

Hence, the original price of the article is Rs.375.

Answer 2

Answer:

hi guys .PLEASE MARK ME AS BRAINLIST

Step-by-step explanation:

ANSWER: Net loss of 4%

SOLUTION:

Let ‘x’ be the original cost price of an article.

Price of the article after decreasing by 20%

= x-(20/100)x = x-0.2x = 0.8x

Final price of the article after increasing later by 20%

= 0.8x + (0.8x)(20/100) = 0.8x + (0.8x)(0.2) = 0.8x + (0.16x) = 0.96x

Net change (gain or loss) in the price = Final sale Price - Original cost Price

= 0.96x -x = (0.96–1)x = -0.04x = -4% of ‘x’
