    The temperature of a body on Kelvin scale is found to be x K. When it is measured by Fahrenheit thermometer, it is found to be \[x{}^\circ \] F, then the value of x is

    A)  30                                         

    B) 313

    C) 574.25                                  

    D)  301.25         

    Correct Answer: C

    Solution :

    \[\frac{F-32}{9}=\frac{K-273}{5}\] But given,   \[{{x}^{o}}F=x\,K\] \[\therefore \]  \[\frac{x-32}{9}=\frac{x-273}{5}\]                 \[5x-160=9x-2457\]                                 \[4x=2297\]                                 \[x=574.25\]
