Question

An alloy contains 34 % Zinc and 42 % Copper and the rest is Nickel . Find in grams the quantity of each of the contents in the sample of 2 kg alloy .​

Answer 1

Answer:

Percentage of Copper=32%

Percentage of Zinc=100-72=28%

So in 1000g of alloy

Copper=1000×32/100=320g

Zinc=1000×40/100=400g

and ,Nickel=1000×28/100=280g....
