Step-by-step explanation:30 percent is zinc...so we can say one third is zinc

similarly in a 3kg alloy also one third is zinc

one third of 3 kgs is one kg

hence one kilogram of zinc is present

Answer 2

According to your question:

let the alloy contains 45% of nickel,25% of copper, rest in zinc

Zn=100-45-25=30%

zinc is present in 3 kg of alloy
