Relative density = Weight of solid in air/(Weight of solid in air – Weight of solid in water)
Substituting the values of the known parameters, we get:
2.5 = Weight of solid in air /( Weight of solid in air – 0.120)
=> 2.5(Weight of solid in air – 0.120) = Weight of solid in air
=>2.5 Weight of solid in air – (2.5 * 0.120) = Weight of solid in air
=>2.5 Weight of solid in air – 0.30 = Weight of solid in air
=>2.5 Weight of solid in air – Weight of solid in air = 0.30
=>1.5 Weight of solid in air = 0.30
=> Weight of solid in air = 0.30/1.5
=> Weight of solid in air = 0.2 kg
