If the reading in Fahrenheit scale is twice the reading in Celsius scale, then the reading in Fahrenheit scale is
- A \(100^{\circ} \mathrm{F}\)
- B \(120^{\circ} \mathrm{F}\)
- C \(80^{\circ} \mathrm{F}\)
- D \(320^{\circ} \mathrm{F}\)
Answer & Solution
Correct Answer
(D) \(320^{\circ} \mathrm{F}\)
Step-by-step Solution
Detailed explanation
\begin{aligned} & \text { Given } \mathrm{F}=2 \mathrm{C} ; \mathrm{C}=\frac{\mathrm{F}}{2} \\ & \Rightarrow \frac{\mathrm{F}-32}{9}=\frac{\mathrm{C}}{5} \Rightarrow \frac{\mathrm{F}-32}{9}=\frac{\mathrm{F}}{2 \times 5} \\ & \Rightarrow 10 \mathrm{~F}-320=9 \mathrm{~F} \\ &…
