How are you getting the same answer as that given in the solution? If the question is trying to ask the total number of bytes that are being sent to B, then I am getting answer as 1700 B.
1st fragment: 456B data+20B header
2nd fragment: 456B data+20B header
3rd fragment: 456B data+20B header
4th fragment: 112B data+20B header
5th fragment: 120B data+20B header
So total number of bytes that are being sent= 1600+(20*5)= 1700B
Shouldnt this be the answer?
