 Prathmesh said: (Dec 2, 2015) || means parallel.

 Balasabarish said: (Dec 29, 2015) Parallel resistance along R2, R3, R4 = 24. Total resistance = R1+ (R2||R3||R4) = 92. Total current = (v/i) = 46/92 = 0.5 A. Voltage drop across R1 = Total current*R1 = 34. Voltage drop across R3 = Source Voltage - Voltage drop across R1. = 46-34 = 12 V.

 Raja said: (Oct 17, 2016) @Balasabarish. Why did you use R1*.5. Should you use R3*.5 rite?

 Rohit said: (Nov 16, 2018) In question, it asked voltage drop at R3 terminal and 24 is the parallel resistance of the circuit.

 Kumar said: (Aug 1, 2019) Parallel resistance along R2, R3, R4 = 24. Total resistance= R1+(R2||R3||R4) = 92, Total current= (v/i)= 46/92 =0.5A, Voltage drop across R3= 24 * 0.5 = 12.
