An alloy contains 32% copper, 40% nickel and rest zinc. Find the mass of the zinc in 1 kg of the alloy. |
|
Answer» Mass of alloy = 1kg = 1000 gm Mass of copper in alloy \(=\frac{1000\times32}{100}\) = 320 gm Mass of nickel in alloy \(=\frac{1000\times40}{100}\) = 400 gm So, amount of zinc in alloy = 1000 - (320 + 400) = 1000 – 720 = 280 gm |
