Rahul should take the help of a litmus paper (both red and blue)
An acid turns blue litmus to red and has no effect on red litmus.
A base turns red litmus to blue and has no effect on blue litmus.
A neutral substance has no effect on both red and blue litmus papers.
Rahul should take the two litmus papers and dip it in each of the drinks.
The drink which turns blue litmus to red is acidic and can be served to customer-1. The drink which turns red litmus to blue is basic and can be served to customer-2. The drink which does not change the color of the litmus papers is neutral and can be served to customer-3.
