Answer 1

As per National standard 1 tap for 10 student is recommended for hand washing  

Explanation:

• Because the microorganism spread from the hand to the tab and the next person who uses the tap gets infected with that bacteria. As a result of this in more developed countries the number of tab is more as compared to the number of students
