MCQ
A faulty thermometer has its lower fixed point marked as $ - \,10^\circ C$ and upper fixed point marked as $110^o $ and upper fixed point marked as $110^o $. If the temperature of the body shown in this scale is $62^o $, the temperature shown on the Celsius scale is ........ $^oC$
  • A
    $72$
  • B
    $82$
  • $60$
  • D
    $42$

Answer

Correct option: C.
$60$
c
(c) $\frac{{X - L}}{{U - L}} = \frac{C}{{100}}$

==> $\frac{{62 - (10)}}{{110 - ( - 10)}} = \frac{C}{{100}}$ $(C = 60^o C)$
