A platinum resistance thermometer reads `0^@` when its resistance is `80 Omega` and `100^@` when its resistance is `90 Omega`. Find the temperature at the platinum scale at which the resistance is `86 Omega`.

Explanation

To solve the problem, we need to use the relationship between the resistance of the platinum thermometer and the temperature. The formula we will use is:

\[ T = \frac{R - R_0}{R_{100} - R_0} \times 100 \]

Where:
- \(T\) is the temperature we want to find,
