Question

If the temperature of a patient is ${40}^{o}C$ his temperature in the Fahrenheit scale will be

• A. ${72}^{o}F$
• B. ${96}^{o}F$
• C. ${100}^{o}F$
• D. ${104}^{o}F$

Answer 1

The correct option is D ${104}^{o}F$

Relation between Degree Celsius and Fahrenheit is,

$\frac{C}{5}=\frac{F-2}{9}$

Now putting $40$ for $C$,

$\frac{40}{5}=\frac{F-32}{9}$

That is,

$F-32=8\times 9$

or

$F=72+32=104$
