It was 2P/3. Once the tap is opened the 2 containers will seemingly become one container, and not ALL the air particles will move from container A to container B, because container A had 200cm3 of air in it, while container B's capacity was only 100cm3. So when 100cm3 of air will move to container B, both their volumes will merge aswell i.e 200cm3 capacity of container A + 100cm3 capacity of container B. Pressure was initially P as they had stated, so final pressure = initial pressure x initial volume/final volume = P x 200/300 = 2p/3. P1V1=P2V2 was never to be applied on this question, even though it gave the correct answer for the lucky ones who used it :p it was a trick question :)
