Answer 1

Answer:

percentage profit = 20%

Step-by-step explanation:

cost of 30 articles  = x = selling price of 25 articles

cost of 1 article  = x/30

selling price of 25 articles = x

selling price of 1 article = x/ 25

cost = ( SP * 100 ) / ( 100 + percentage profit )

x/ 30 =( x/ 25 *100)/ ( 100 + percentage profit )

x/ 30 = 4x /( 100 – percentage loss )

100 + percentage profit = 4x/ x/30

100 + percentage profit= (4x *30)/x

100 + percentage profit = 4*30

100 + percentage profit = 120

percentage profit = 120-100

percentage profit = 20%
