# Thread: Alloy A copper:zinc = 5:2, Alloy B zinc:tin = 3:2; 2 parts A, 1 part B form new alloy

1. ## Alloy A copper:zinc = 5:2, Alloy B zinc:tin = 3:2; 2 parts A, 1 part B form new alloy

Urgently need solution of this question as soon as possible:

An alloy contains copper and zinc in the ratio 5:2 and another contains zinc and tin in the ratio 3:2. if two parts of 1st alloy and one part of 2nd alloy are melted together to form a new alloy of copper, zinc and tin, the ratio of the metals will be?

2. What have you tried or thought about, so far?

How many pounds of alloy 1 will give me integer amount of copper and integer amount of zinc.

Looks like 7 pounds of first alloy give me 5 pounds of copper and 2 pounds of Zn.

Next I'll ponder the statement - "two parts of 1st alloy and one part of 2nd alloy are melted together"....
