A vendor buys milk at a certain price, adds water and sells the adulterated milk at the same rate as he bought it for. He makes a 30% profit. What is the percentage of water that he adds to milk?
The correct option is A): "30%" because suppose vendor bought 100 ltr milk at 10/ltr so cost price =1000 rs. In that he adds "x" ltr of water in order to get profit of 30% above cost price , means his total earnings from adulturated solution will be 1300 rs.
