हिन्दीAt what temperature do the numerical values on the Fahrenheit scale and the Celsius scale become identical?
Correct answer · Option 1
\( -40^\circ \)
Explanation
Using \( ^\circ\text{F} = \frac{9}{5}(^\circ\text{C}) + 32 \), setting \( ^\circ\text{F} = ^\circ\text{C} = x \) gives \( x = \frac{9}{5}x + 32 \implies x = -40^\circ \).
