So if there is a tie, than it will match with destination.
If there is still a tie like this case than it chooses the first ip address (which is 175.15.10.140).

Example of closest match (longest bit match)
IP 1: 175.15.10.140
IP2: 175.15.10.141
Default gateway: 175.15.10.129

Last Octet match
140 = 10001100
141 = 10001101
129 = 10000001

So we have the tie , After the tie than it will match with destination.

If still there is a match than it takes the first IP address in our case 175.15.10.140
