Question

If the temperature of a patient is ${40}^{\circ }C$, his temperature on the Fahrenheit scale will be

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

Answer 1

The correct option is B ${104}^{\circ }F$

We know that: $\frac{C-0}{100-0}=\frac{F-32}{212-32}$

Given: $C={40}^{\circ }C$

$\frac{C-0}{100}=\frac{F-32}{212-32}$

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

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

$360=5F-160$

$F={104}^{\circ }F$
Final answer (d)
