Correct answer is D
Relative density of solid
weight of solidweight of an equal volume of water
= 4.84.8−2.8
= 4.82 = 2.4
Relative density of liquid
= Weight of liquid kerosineWeight of an equal volume of water
= 4.8−3.24.8−2.8 = 1.62 = 0.8
= Ratio of relative density of solidRelative density of Kerosine
= density of soliddensity of Kerosine
= 2.40.8
= 3
