If a body is compressed to half it's previous volume, what will be the effect on it's density and why?

Neerajdhiman1: i think density will be double .because density is inversly to volume

$density = \frac{mass \: }{volume} \\ \: \\ suppose \: originally \: its \: volume \: was \: v \\ \\ so \\ its \: d = \frac{m}{v} \\ now \: volume \: become \: \frac{1}{2} v \\ so \: new \: density \: is \: d' \\ d' = \frac{m}{ \frac{v}{2} } \\ d' = \frac{2m}{v} \\ now \: new \: density \: become \: twice \: of \: previos \: one. \\d ' = 2d$

harshitgrover2pd1n28: Let initial vloume = v and final volume = v/2 and density=mass/volume so density initial =m/v and final density=m/v/2=2m/v and m/v is equal to initial density that means ::: final density=2 initial density and it is due to decrease in volume which cause molecule tightly fit and increase in denaity..
