MCQ
A thermometer graduated according to a linear scale reads a value $x_0$ when in contact with boiling water, and $x_0/3$ when in contact with ice. What is the temperature of an object in ${}^oC$, if this thermometer in the contact with the object reads $x_0/2$ ?
  • ✓
    $25$
  • B
    $60$
  • C
    $40$
  • D
    $35$

Answer

Correct option: A.
$25$
a
$t = \frac{{{x_t} - {x_0}}}{{{x_{100}} - {x_0}}}{100^ \circ }C$

$\frac{{\frac{{{x_0}}}{2} - \frac{{{x_0}}}{3}}}{{x - \frac{{{x_0}}}{3}}}{100^ \circ }C$

$ = {25^ \circ }C$

This question contains Statement$-1$ and Statement$-2$. Of the four choices given after the statements, choose the one that best describes the two statements.
