Question

an article bought 54/-per dozen and sold it 85/-per score find loss or gain percent answer 27.50​

Answer 1

cost price of article per dozen(12) = 54

cost price of one article = 54/12

selling price of article per dozen = 85

selling price of one article = 85/12

profit = sp - cp

= 85/12 - 54/12

= 85-54/12

= 31/12

profit percent = profit / cost price *100

= (31/12)/(54/12)*100

=(31/12*12/54)*100

= (31/54)*100

= 57.4%
