An alloy is

In two alloys the rations of copper to tin are 3:4 and 1:6 respectively. If 7 kg. of the first alloy and 21 kg. of the second alloy are mixed together to form a new alloy, then the ratio of copper to tin in the new alloy is :

60 kg of an alloy A is mixed with 100 kg of alloy B. If alloy A has lead and tin in the ratio 3 : 2 and alloy B has tin and copper in the ratio 1 : 4, then the amount of tin in the new alloy is

60 Kg of an alloy A is mixed with 100 kg of alloy B .If alloy A has lead and tin in the ratio 3:2 and alloy B has tin and copper in the ratio 1:4 , the amount of tin in the new alloy is .

An alloy contains only zinc and copper and they are in the ratio of 7:9. If the weight of the alloy is 8kg ,then find the weight of copper in the alloy.
