Answer 10

sorry this is again wrong

Answer 11

density=mass/volume
Mass decreases by 5% => new mass = (95/100)m
Density increases by 2% => new density = (102/100)d
So, new volume = new mass/ new density = (95/102)v
Change in volume = v - (95/102)v = (7/102)v
Percent change = (7/102) x 100 = 6.86 %
