Question

if selling price of an article is 638 and profit is 45% then what will be the net profit​

Answer 1

Answer:

Rs 198

C.P.= S.P. - profit

= Rs(638-profit)

now, profit %= (profit/C.P).×100

45={profit/(638-profit)}×100

45/100=profit/(638-profit)

9/20(638-profit)=profit

(9/20)×638 - (9/20)xprofit = profit

5742/20=profit+(9/20)profit

5742/20=(29/20)profit

5742/20×20/29=profit

profit=5742/29

= 198
