Question:
Dorji has a few bottles of soft drink in his restaurant. But, unfortunately, these are not labelled. He has to serve the drinks on the demand of customers. One customer wants acidic drink, another wants basic and third one wants neutral drink. How will Dorji decide which drink is to be served to whom?

Answer:

Drinks are eatable material so Dorji can check the medium of the drinks by tasting them, acid drink will be of souring taste, basic will be bitter in taste and neutral will not contain any taste. So, just by tasting and drinking them, we can serve the drinks on the demand of the customers.

Note*: He can check the drinks medium of the drinks by using the litmus paper by putting one drop of each drinks on it. He can conclude which is acidic, basic and neutral.
