Two thermometers $X$ and $Y$ have ice points marked at $15^o$ and $25^o$ and steam points marked as $75^o$ and $125^o$ respectively. When thermometer $X$ measures the temperature of a bath as $60^o$ on it, ..... $^oC$ would thermometer $Y$ read when it is used to measure the temperature of the same bath ?

A

$60$

B

$75$

C

$100$

D

$90$

Solution

For any temperature scale

$\frac{\text { Reading – ice point }}{\text { Steam point-ice point }}=$ constant

Solve for the two thermometers.
