There's not enough info to complete this.
I can try to give you every variable possible:
NC=12
RS=4
SC=6
NC/SC=12/6=2
N/S=2
N=2S, S=N/2
RS=RN/2=4 => RN=8, R=8/N
The question is an illustration of similar triangles.
The value of MN is 8
From the figure, we have the following equivalent ratios:
[tex]MN : NC = RS : SC[/tex]
So, we have:
[tex]MN : 12 = 4 : 6[/tex]
Express the ratio as fraction
[tex]\frac{MN }{ 12} = \frac{4}{ 6}[/tex]
Multiply through by 12
[tex]MN =8[/tex]
Hence, the value of MN is 8
