Answer 2

Answer:

Milk man profit on 1 litre milk= 20 rupees.

Loss=30rupees on every 1 litre of milk, which is not sold.

Step-by-step explanation:

(I) He sells 18 litre therefore,

profit gained by him=20×18= 360 rupees

Loss made by him=30×7=210 rupees

(ii) Here we know that profit=loss

so, if he didn't sold 6 litre milk so he will make loss of 30×6 rupees that is 180 rupees

therefore profit=180 rupey as profit= loss

so how many liter did he sold= ?

=180/20

=9 litres
