Students passed in English = 80%

Students passed in Math's = 85%

Students passed in both subjects = 73%

Then, the number of students who passed at least one subject

= (80+85)-73

= 92%.

[The percentage of students who passed in English and Maths individually, has already included the percentage of students who passed in both subjects. So, We are subtracting the percentage of students who have passed both subjects to find out the percentage of students who at least passed one subject.]

Thus, students failed in both subjects = 100-92 = 8%.

Explanation

Mercury is used as a thermometric fluid because it has several ideal properties:

1. High Boiling Point (B.P)

   • Mercury doesn't evaporate easily, which makes it suitable for measuring high temperatures.

2. Low Freezing Point (not high M.P)

   • Mercury has a low melting point (−38.83°C), which helps in measuring low temperatures, though this limits it in very cold environments.

3. Stable and Uniform Coefficient of Expansion

   • Mercury expands uniformly with temperature, which gives accurate and consistent readings.

4. Visibility and Non-wettability

   • Mercury is shiny and opaque, so it's easy to see in a glass tube.

   • It doesn't stick to glass, which keeps the readings clean and precise.
