An alloy contains 20% of copper , 35%of zinc and rest as nickle .In 1.5kg alloy , what is the quantity of nickle ?
percentage of nickel = 100-(20+35)
=45 %
let x be the quantity of nickel in alloy
(x/1.5)*100 = 45
x/1.5 =0.45
x=0.675 kg
quantity of nickel in 1.5 kg alloy =0.675 kg
cheerss....!!!! :)
