    What temperature will have the same reading   on Fahrenheit scale and also on Kelvin scale?

    A) \[574{}^\circ \]                                 

    B) \[590{}^\circ \]

    C) \[287{}^\circ \]

    D) \[-80{}^\circ \]

    Correct Answer: A

    Solution :

                    Using the relation, \[\frac{F-32}{180}=\frac{K-273}{100}\]                 So,          \[\frac{\theta -32}{{{180}^{o}}}=\frac{\theta -273}{100}\]                                 \[100\theta -3200=180\theta -49140\]                                 \[80\theta =45940\]                 So,          \[\theta =574.25\]                 or            \[\theta ={{574}^{o}}\]
