A 200 mL of 30% (V/V) of a solution is mixed with 500 mL of 40% (V/V) another solution. What is the volume percentage of resultant solution?

A solid mixture weighing $5 \text{ g}$ contains equal number of moles of $\text{Na}_2\text{CO}_3$ and $\text{NaHCO}_3$. This solid mixture was dissolved in $1 \text{ L}$ of water. What is the volume (in $\text{mL}$) of $0.1 \text{ M } \text{HCl}$ required to completely react with this $1 \text{ L}$ mixture solution?

Two liquids 'A' and 'B' form an ideal solution. At 300 K, the vapour pressure of a solution containing 1 mole of 'A' and 3 moles of 'B' is 550 mm Hg. At the same temperature, if one more mole of 'B' is added to the solution, the vapour pressure of solution increases to 560 mm Hg. Then the ratio of vapour pressures of A and B in their pure state is
