A______B

15(Alloy A ka silver )_______25(Alloy B ka silver )

____ 18(resultant)____

7________3

7:3

The amount of zinc is same in both the alloy A and B :

Then the resultant zinc percentage is

(7*60 + 3*60)/(7+3) = 60%.

So, copper percentage = 100 – (60 + 18) = 22

The ratio of these metals = 60 : 22 : 18
