Question

On a hilly region, water boils at $95 \,{}^\circ C$ . The temperature expressed in Fahrenheit scale is

• A. $100^\circ F$
• B. $200^\circ F$
• C. $150^\circ F$
• D. $203^\circ F$

Answer 1

Answer: (D)

If the temperature of a body on Celsius and Fahrenheit scales are recorded as C and F respectively, then
$ \, \, \frac{C - 0}{100 - 0} \, \, = \, \frac{F - 32}{212 - 32}$
or $ \, \, \frac{C}{5} \, =\frac{F - 32}{9}$
Here, $ \, \, C=95^\circ C$
$\therefore $ $\frac{95}{5} \, = \, \frac{F - 32}{9}$
Or $5F \, = \, 1015$
$\therefore $ $ \, \, \, F=\frac{1015}{5} \, =203^\circ F$
