Answer:
Alloy A has less% of copper.
Step-by-step explanation:
Alloy A (30g of nickel and 12g of copper
total=42g).
Alloy B (15g of nickel and 9g of copper
total=24g).
When we add 15g nickel and 9g copper in Alloy B it will be
30+18=48
where Alloy A has 30g of nickel and 9g of copper.
therefore Alloy A has less% of copper.
