A student put two eggs A and B in HCL solution, After five minutes he took them out for weighing but egg dropped in water accidentally. The student was able to take it out after 30 minutes, He weighed it, Its weight was 40.33g. Weight of egg B was also 40.33g. Teacher told him that if both eggs have been dropped in water, the weight of egg B would have been:
