A solution is prepared by dissolving $\displaystyle 0.3$ g of a non-volatile non-electrolyte solute 'A' of molar mass $\displaystyle 60 \mathrm{~g} \mathrm{~mol}^{-1}$ and $\displaystyle 0.9$ g of a non-volatile non-electrolyte solute 'B' of molar mass $\displaystyle 180 \mathrm{~g} \mathrm{~mol}^{-1}$ in $\displaystyle 100 \mathrm{~mL} \mathrm{H}_2 \mathrm{O}$ at $\displaystyle 27^{\circ} \mathrm{C}$. Osmotic pressure of the solution will be [Given: $\displaystyle \mathrm{R}=0.082 \mathrm{~L} \mathrm{~atm} \mathrm{~K}^{-1} \mathrm{~mol}^{-1}$ ]
