Answer:
Current drawn = 0.417 A (rounded to 3 significant figures)
Resistance = 576Ω (rounded to 3 significant figures)
Explanation:
Current = Power ÷ Voltage
Current = 100W / 240V
∴ Current = 0.416666666.... = 0.417A
Resistance = Voltage ÷ Current
Resistance = 240 ÷ 0.417
∴ Resistance = 575.539 = 576Ω
