Question

The maximum temperature on a day is ${35}^{\circ }C$ and the minimum temperature is ${25}^{\circ }C$. The difference of these temperatures on Fahrenheit scale is:

• A. ${25}^{\circ }F$
• B. ${75}^{\circ }F$
• C. ${50}^{\circ }F$
• D. ${100}^{\circ }F$

Answer 1

The correct option is C ${50}^{\circ }F$

Difference of temperatures in Celsius is

${35}^{\circ }C-{25}^{\circ }C={10}^{\circ }C$
Now to convert Celsius into Fahrenheit, multiply temperature in degree Celsius by $\frac{9}{5}$ and then add $32$

$\therefore {10}^{\circ }C=(10\times \frac{9}{5})+32$ $=18+32={50}^{\circ }F$

Hence the answer is ${50}^{\circ }F$.
