In the given question, R1, R2 and R3 are in series and R4 is in parallel with any one. So for example R4||R3.

Now R1 and R2 in series 10+10 = 20 k and from R3 and R4 = 6.66 k, which is now in series with R1 and R2.

Then Rt is 26.66 k.

To find I = v/r.

I = 24v/26.66k = 0.900 mA = 900 uA.

Three 10k in series but one 10k in parallel with 20k = 10*20/30 = 6.66 k + 20 k = 26.66 k.

I = 24/26.66 k = 900 uA.

Here,

R = 20k||10k + 20k.
I = 24/R.
