Answer
$R_1 = 3 + 2 = 5$ ohm
$R_2 = 30 W$
$R_3 = 6 + 4 = 10$ ohm
$R _1, R _2$ and $R _3$ are connected in parallel
$\frac{1}{ R }=\frac{1}{ R _1}+\frac{1}{ R _2}+\frac{1}{ R _3}$
$=\frac{1}{5}+\frac{1}{30}+\frac{1}{10}=\frac{10}{30}$
$R = 3 ohm$
$R_2 = 30 W$
$R_3 = 6 + 4 = 10$ ohm
$R _1, R _2$ and $R _3$ are connected in parallel
$\frac{1}{ R }=\frac{1}{ R _1}+\frac{1}{ R _2}+\frac{1}{ R _3}$
$=\frac{1}{5}+\frac{1}{30}+\frac{1}{10}=\frac{10}{30}$
$R = 3 ohm$
