A trader uses a 110 cm scale while buying cloth and uses a 90 cm?
Statement of the given problem, A trader uses a 110 cm scale while buying cloth and uses a 90 cm scale when selling the cloth. He further provides a 10% discount to cost price. What is his overall profit percentage? Let C & S denote the cost price & selling price per meter of cloth respectively. Hence from above data we get following relation, (90/100)*S = (1 - 10/100)*(110/100)*C or 9*S = (9/10)*11*C or S = (11/10)*C or S = (1 + 1/10)*C or S = (1 + 10/100)*C Therefore from above it is evident that the required overall profit percentage is 10%.
