A fahrenheit thermometer reads  ${113}^{0}F$ while a faulty Celsius thermometer reads  ${44}^{0}C$ one correction to be applied to the Celsius thermometer is

$\mathrm{relation} \mathrm{between} \mathrm{celsius} \mathrm{and} \mathrm{fahrenheit} \mathrm{thermometer} \mathrm{is}$

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

$\frac{\mathrm{C}}{5}=\frac{113-32}{9}$

$$\begin{gathered} \mathrm{C}={45}^0 \\ \mathrm{\Delta C}=45-44 \end{gathered}$$

$=+1^0\mathrm{C}=\mathrm{correction} \mathrm{to} \mathrm{be} \mathrm{applied} \mathrm{to} \mathrm{the} \mathrm{celsius} \mathrm{thermometer}$
