A. 2
B. 3/2
C. 2/3
D. 3

Correct Answer:

Option D = 3

Explanation

Relative density of solid= weight of solid/weight of an equal volume of water

= 4.8/4.8−2.8

= 4.8/2 = 2.4

Relative density of liquid = Weight of liquid kerosene/Weight of an equal volume of water

= 4.8−3.2/4.8−2.8 = 1.6/2 = 0.8

= Ratio of relative density of solid/Relative density of Kerosene

= density of solid/density of Kerosene

= 2.4/0.8

= 3
