Apply nodal equation to the circuit.

[v-75]/68+v/68+v/120 = 0.

We get v = 29.22.

In = v/r.

In = 29.22/120.

In = 0.2435A.

In is the Norton Equivalent current source, to find that :

Short the points A-B and then find the current drawn from the source. This gives the value of In. Answer comes out to be 673.22mA, close to A.

It can be solved by Thevenin's theorem. But have to ignore value of RL in equation. IL = vth/Rth+RL.

Apply to KVL & solve it.
equations are:-
75-68I1-68I2=0.......(i)
-120I1+188I2=0.......(ii)
solve two equations....& same current flow in R3 & RL
i.e. I1-I2=242mA (Approx.)

I think you should use thevnin theorem. That means find Vn by opening AB and find Rn by shorting AB. Finally divide Vn / Rn = In.

Apply KCL to both loop, then solve those two equations, then the current i2 will be the answer, i.e=0.436A.

RL represent the Load, using nortons theorem, you remove the load and find the current through R3.
