First time post so I appreciate any help because this one is hurting my head!!!

So I am trying develop a project priority list which consist of 10 projects (Project 1 - Project 10), I ask my peers to rank the 10 projects based on importance to the company and return them to me. I am now trying to take their rankings and consolidate them to a final ranking. Could someone please help me with the formula needed to accomplish this including tie breakers if not too difficult? Thanks in advance!

A B C D E F
Project Peer 1 Peer 2 Peer 3 Peer 4 Peer 5
Project 1 1 3 2 9 5
Project 2 2 4 1 7 6
Project 3 3 7 3 3 2
