Relative density = mass of liquid displaced Γ· mass of water displaced
2 = m - 10/ m-15
2m - 30 = m - 10
m = 30 - 10 = 20g

You can also use R.D=Upthrust in liquid/upthrust in water
Since we are given mass
upthrust=mg
mass of water=10g
mass of liquid=?
u=mg
R.D=mx10/10x10
2=10m/100
10m=200
Divide both side by 10
m=20g
