Question
A dishonest trader marks up his goods by 50% and then
allows a discount of 20% on its marked price. Additionally, he uses a faulty scale which measures 900 gm. for 1 kg. shows. What will be his net profit percentage (rounded off to the nearest integer)?Solution
Let the original CP = 100 Dishonest traders mark -up = 50% so, mark price = 100+50=150 discount = 20% SP = (150×80)/100 SP = 120 Now- faulty scale which measures 900 gm. for 1 kg. CP=90 profit% = {(120-90)/90} ×100 =33.33% =33%
