Question

An alloy contains copper, zinc and tin in the ratio 4:5: 6 respectively. Another alloy containing copper and tin is melted and mixed with the first alloy. If the mixture contains copper, zinc and tin in the ratio 13:1:3, find the ratio of copper and tin in the second alloy. 12:5 9:25 25:9 61:9 None of these

Answer 1
