Answer 2

Answer:

Dorji will decide which drink is to be served to whom (customer) by doing the following litmus paper tests : (i) If the drink turns blue litmus paper to red, then the drink is acidic and hence will be served to first customer who wants acidic drink. (ii) If the drink turns red litmus paper to blue, then the drink is basic and hence will be served to another customer who wants basic drink. (iii) If the drink shows no change in colour with litmus paper, then it will be neutral drink. Thus, it will be served to third customer. Since, the soft drinks are edible. Dorji can take the decision by tasting the drinks. Acidic drinks will be sour to taste whereas basic drinks will be bitter to taste and neutral drinks will have no taste.
