Question

A faulty thermometer has its fixed points marked $5$ and $95$ If the temperature of a body as shown on the celcius scale is $40$ then its temperature shown on this faulty thermometer is .

Answer 1

faulty reading $\left(x\right)=59$

Lower fixed point of faulty reading $(L.F.P)=5$

Upper fixed point of faulty reading $(U.F.P.)=95$

Fundamental interval $(F.I.)=95-5=90$

Correct reading $\left(C\right)=?$

$\frac{c}{100}=\frac{(x-L.F.P)}{F.I.}$

$\frac{c}{100}=\frac{54}{90}$

$C=0.6\ast 100=60$ celsius scale.
