A) \[-{{48}^{o}}\]
B) \[-{{40}^{o}}\]
C) \[{{37}^{o}}\]
D) \[{{40}^{o}}\]
Correct Answer: B
Solution :
The relation between the Centigrade and Fahrenheit scale of temperature is \[\frac{C}{5}=\frac{5-32}{9}\] Suppose,\[x\]be the temperature at which Centrigrade and Fahrenheit scales are equal. Hence, \[\frac{x}{5}=\frac{x-32}{9}\] \[9x=5x-160\] \[4x=-160\] \[x=-{{40}^{o}}\]You need to login to perform this action.
