Sana and Priya measure their body temperature using thermometers. Sana recorded her body temperature to be 98.6 °F while Priya recorded hers to be 38.4 °C.
Which of the following statement is true ?
Answer: D
The true statement is that body temperature of Priya is more than that of Sana.
Convert Priya's reading to Fahrenheit:
\[ \begin{aligned} F &= \frac{9}{5}C + 32 \\ &= \frac{9}{5}(38.4) + 32 \\ &= 101.12^\circ\text{F} \end{aligned} \]
Sana's 98.6°F is 37°C, normal body temperature, while Priya at 101.12°F (38.4°C) is higher, and in fact has a fever. So their temperatures are not the same, only Priya has fever, and Sana's is not the higher one.
