An oleum sample has ${\mathrm{SO}}_3$ and ${\mathrm{H}}_2{\mathrm{SO}}_4$ in 2 : 3 mass ratio. Select the correct statement(s).

% labelling of sample is 118%

% labelling of sample is 109%

If 9 gm ${\mathrm{H}}_2\mathrm{O}$ is added to 200 gm of above sample new labelling would be 104.3 %

If 9 gm ${\mathrm{H}}_2\mathrm{O}$ is added to 200 gm of above sample new labelling would be 104.5 %
