Question

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

Answer 1

Answer: (C)

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