Question

The apparent coefficient of expansion of liquid, when heated in a copper vessel is C and when heated in a silver vessel is S. If A is the linear coefficient of expansion of Copper, linear expansion coefficient of silver is

$\frac{C + S - 3 A}{3}$
$\frac{C + 3 A - S}{3}$
$\frac{S + 3 A - C}{3}$
$\frac{C + S + 3 A}{3}$

The correct answer is: $fraction numerator C plus 3 A minus S over denominator 3 end fraction$
