Which of the following figures represents the relation between Celsius $(C)$ and Fahrenheit $(F)$ temperatures?

On a linear temperature scale $Y$,water freezes at $-160^{\circ}Y$ and boils at $-50^{\circ}Y$. On this $Y$ scale,a temperature of $340\,K$ would be read as........ $^{\circ}Y$ (water freezes at $273\,K$ and boils at $373\,K$).

The temperature of a body on the Kelvin scale is found to be $x \ K$. When it is measured by a Fahrenheit thermometer,it is found to be $x \ ^\circ F$. Then the value of $x$ is:

Standardisation of thermometers is obtained with

If the two temperatures on the Fahrenheit scale differ by $54^{\circ}\text{F}$, then the difference in temperature on the Celsius scale is (in $^{\circ}\text{C}$)

The melting point of ice and the boiling point of water are marked as $20^o X$ and $150^o X$ respectively on a thermometer. What will be the temperature of $60^o C$ on this scale?
