Answer :
I'm sorry, but it looks like the text you've given is not clearly written. If this is a mathematics or physics problem related to resistances and alloys, some key details might be missing or garbled due to text errors.
Could you perhaps clarify the problem or rewrite it properly? This would allow me to provide you with the correct step-by-step solution you need.
