An alloy contains copper, zinc, nickel in the ratio of 5:3:2.The quantity of nickel in kg that must be added to 100 kg of this alloy to have the new ratio 5:3:3

• In 100kg alloy
  
  copper=50kg
  zinc=30kg
  nickel=20kg
  
  If we hav to do this mix as 5:3:3 then we hav to add 10kg-nickel.

• let x kg of nickel is added to 100 kg of alloy.
  and in 100 kg of alloy we have 20 kg of nickel.
  hence, after adding x kg of nickel, x+20=(100+x)*3/(5+3+3)
  on solving we get, x=10 kg

• Given alloy contains copper,zinc,nickel in the ratio 5:3:2,given alloy has 100kg initially Therefore 5x+3x+2x=100 =)x=10 So in the alloy nickel quantity is 20kg
  Therefore quantity of nickel in kg that must be added to 100 kg of this alloy to have the new ratio 5:3:3 = 20+y/100=30/100 =) y=10
  Quantity to nickel to be added=10kg
