A solid weighs 4.8g in air, 2.8g in water and 3.2g in kerosine. The ratio of density of the solid to that of the kerosine is
12
3
2
32
54
Correct answer is B
Relative density of solid = weight of solidweight of an equal volume of water
4.84.8−3.2 = 4.82 = 2.4
Ratio of density of liquid = weight of liquid kerosineweight of an equal volume of water
= 4.8−3.24.8−2.8 = 1.62
= 0.8
= density of soliddensity of kerosine
= 2.40.8 = 3
