JEE Main 2026 Chemistry question

At , 2 moles of liquid A and 3 moles of liquid B are mixed. The vapour pressure of ideal solution formed is 320 mm Hg. At this stage, one mole of A and one mole of B are added to the solution. The vapour pressure is now measured as 328.6 mm Hg. The vapour pressure (in mm Hg) of A and B are respectively:

• (1)300, 200
• (2)600, 400
• (3)400, 300
• (4)500, 200Correct
