Answer:

42kg of zinc

Step-by-step explanation:

by process we can do as:

Cu:Zn:Ni= 4x:3x:2x.

so total = 4x + 3x + 2x = 9x = 54 kg

x = 6

So Cu 24 kg, Zn 18 kg , Ni 12 kg.

In the next case Cu and Ni quantiy will remain same i.e 24kg n 12 kg in 2:1 ratio

To have ratio 2:5:1..... multipy 12*5= 60

total Zinc = 60 kg

therefore Zinc added= 60- 18 = 42 kg
