Question

An alloyof metal contains 45percent nickel , 25percent copper and rest is zink . How much zink is there in 3kg alloys ?

Answer 1

Answer:

According to the question,

Let the alloy contains 45% nickel, 25% copper and

rest in zinc.

Zn=100−45−25

=30%

Since 1kg=1000gm

Therefore,

45×1000=450gofNi;

25×1000=250gofCu,

30×1000=300gofZn

Hence, 3kg

3000g×3=900gofZn present in 3 kg of alloy.
