Answer

Given data:

Suppose an application generates chunks of 40 bytes of data every 20 msec, and each chunk gets encapsulated in a TCP segment and then an IP datagram

That means, TCP segment and IP datagram are 20 bytes each.

Assume to added to the 40 byte to each chunk makes 2*40=80 total bytes.

The over head is 40 of the 80 total, that means 50%.

So,  the percentage will be application data 50%
