Apply KVL in loop (1)
\mathrm{ 20-10-10 \mathrm{I}=0 }
Or \mathrm{ I=1 \mathrm{Amp} }
Apply KVL in loop (2)

\mathrm{-10+5 I^{\prime}=0 }
\mathrm{ \text { Or } I^{\prime}=2 \mathrm{Amp} }
On comparing \mathrm{I}_3=1 \mathrm{~A}
\mathrm{I}_2=\mathrm{I}_1=\frac{\mathrm{I}^{\prime}}{2}=1 \mathrm{Amp}
So, the value of \left|\frac{\mathrm{I}_1+\mathrm{I}_3}{\mathrm{I}_2}\right|=\left|\frac{1+1}{1}\right|=2 \mathrm{Amp}.
