Answer 2

Iron = 1.2 kg , Zinc = 1.8 kg  when an 3kg alloy of iron and Zinc contains 40% of iron and the rest is zinc

Step-by-step explanation:

alloy of iron and Zinc contains 40% of iron and the rest is zinc

Iron   40 %

Zinc = 100 - 40 = 60 %

Weight of Iron in 3kg  = (40/100) * 3  =  1.2 kg

Weight of Zinc in 3 kg = (60/100) * 3 = 1.8 kg

Iron = 1.2 kg

Zinc = 1.8 kg
