Q. The Fahrenheit and Kelvin scales of temperature will give the same reading at
A) $- 40$
B) 313
C) 574.25
D) 732.75
Explanation
(c) Let $F = K - X$
As $\frac{F - 32}{9} = \ \frac{K - 273}{5\ }$
$\therefore\ \frac{x - 32}{9} = \frac{x - 273}{5}$
$9x - 2457 = 5x - 160$
$4x - 2457 + 160 = 0$
$x = \frac{2297}{4} = 574.25{^\circ}$
