Q.No.7

A data packet of size 1500 bytes is to be transmitted over a network crossing 2 routers in between. Each network layer adds a header of 20 bytes. The packet is then encapsulated by a data link layer that adds a header of 30 bytes and a trailer of 10 bytes. What is the total size of the packet, including all headers and the data payload?
