Equal masses of water & liquid of density 2 are mixed together, then the mixture has a density of:a) 2/3 b) 4/3 c) 3/2 d)3

Dear Mainak

volume of water is =m/1
volume of liquid is = m/2
after mixing   mass of the mixture = (2m)
after mixing volue of mixture =(m+.5m)=1.5m
so density =2m/1.5m
    = 4/3
