A faulty thermometer has its fixed points marked $5^o$ and $95^o$. This thermometer reads the temperature of a body as $59^o$. Then, the correct temperature of the body on the Celsius scale is ...... $^o$

A

$59$

B

$60$

C

$48.6$

D

$58$

Solution

$\frac{59^{\circ}-5^{\circ}}{95^{\circ}-5^{\circ}}=\frac{\mathrm{C}-0}{100-0}$

$C=60^{\circ}$
