Question

A Fahrenheit thermometer registers ${107}^{o}F$ while a faulty Celsius thermometer registers ${42}^{o}C$. Find the error in the later

• A. ${0.37}^o$
• B. ${0.87}^o$
• C. ${0.33}^o$
• D. $48$

Answer 1

The correct option is C ${0.33}^o$

Given

Temperature of fahrenheit scale= 107 F

Temperature on faulty celsius scale= 42 C

Solution

$C=\frac{5}{9}\times (F-32)$

Put F=107

$C=41.66C

Error= 42-41.66

$={0.33}^{o}C$

$D$ is the correct option
