Question

Fahrenheit and Celsius are the two scales used for measuring temperature. If the numerical value of a temperature recorded in both the scales is found to be same, what is the temperature?

• A. $-{40}^o$
• B. $+{40}^o$
• C. $+{72}^o$
• D. $-{72}^o$

Answer 1

The correct option is A $-{40}^o$

Let T be the temperature.

F= $\frac{9}{5}C+32$

put F=C=T

T=-40
