```							Dear student See the explanation here. The masses of two liquids are equal, let it be m.Let the relative densities of water and liquid be ρ1  and ρ2 respectively.The volume of the two be V1 and V2, of water and liquid respectively.The volume of the mixture would be, V = V1 + V2  (1)also, volume = mass/density thus, 2m/ρ (V) = m/ρ1 (V 1 ) + m/ρ2 (V 2 )here ρ1 = 1, ρ2 = 2 and ρ is the relative density of the mixture.now,2/ρ = 1/ρ1 + 1/ρ2by substituting the values, we ρ/2 = 2/3or, the relative density of the combined liquid will be, ρ= 4/3
