Question

If the temperature of a body in both celsius scale and fahrenheit scale are equal. Calculate its temperature.

Answer 1

we know that , $9C=5(F-32)$

Where C is temperature in Celsius and F is in Fahrenheit

Let the common be T , since both temperature in both scale are same

So $9T=5(T-32)$

$4T=-5\times 32$

$T=-40$

At $-{40}^o$, both scale will be same.
