Either it could be AC or DC. How we can judge its AC and assume 230 V?
Please, someone explain.

I = V/R.
Normal AC input Voltage = 230 V.
R1 = 220 ohm.
R2 = 470 ohm.
R3 = 560 ohm.
230/220 = 1.04 A.
230/470 = 0.48 A.
230/560 = 0.41 A.
So, here we can Understand that R3 is having a least current than R1 & R2.

Resistance is inversely proportional to current.

Because voltage is same in case of parallel. So whose resistance is more having the least resistance.
R= (V/I) follow this principle.
R= (V/I) follow this principle.
