(x-10/130-10)=(40/100) 100 x-1000=4800 100 x=5800 x=58°

Q. In a mercury thermometer, the ice point (lower fixed point) is marked as $1 0^{\circ}$ and the steam point (upper fixed point) is marked as $13 0^{\circ}$ . At $4 0^{\circ} C$ temperature, what will this thermometer read?

$7 8^{\circ}$

$6 6^{\circ}$

$6 2^{\circ}$

$5 8^{\circ}$

$\frac{x - 10}{130 - 10} = \frac{40}{100}$
$100 x - 1000 = 4800$
$100 x = 5800$
$x = 5 8^{\circ}$
