What is the current total flow through the network? $[3$ marks$]$

$($ii$)$ Consider the cut consisting of edges $($v$3,$ v$6),($v$4,$ v$6)$ and $($v$5,$ v$7).$ What is the

capacity of this cut? $[3$ marks$]$

$($iii$)$ Briefly explain why any flow through a network is less than or equal to the

capacity of any cut. State the max$-$flow$/$min$-$cut theorem.
