explain plzzz​

Answer 1

Answer:

Co of article=800

gain=12.5%

then,sp=100+gain%/100×cp

100+12.5/100×800=900

let marked price of article be x

then,discount=10%of x

Rs (x×10/100)=1x/10

sp=(mp) - (discount)=x-1x/10=9x/100000

but the sp=Rs.900

so,9x/10=900=1000

Hence , the marked price of an article be Rs.1000
