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....!!!! :)

 Let the amount of nickel be x

Also, %of nickel = 100 - (20+35) = 45

So, x = 45/100 * 1.5

  = 0.675

So, quantity of nickel is 0.675 kg or 675 g
