the question says what is the total volume of AIR in the jar, so as air can be compressed then it should obviously contain 450cm3 and I never heard of glass being flexible in other words the 50cm3 of air in the jar is not going to disappear or fly away so ans is D

Ans 8:

Satvik Agrawal from Delhi Public School, bhopal
Class : Class 5
plz dont be angry. The volume of the glass jar will not change. it will remain the same as it is not flexible. so if we compress air of 50cm3 the volume will decrease. But air occupies the available space. So, the correct answer is C.

Yajat is correct because if you read the question carefully , it is written '30 ml of watter' which means that it was already filled with 30 ml of water. now x=50-30=20cm3 and y =75 - 50 = 25 mlSo correct option is c.
