Question

There are two alloys A and B, both are made up of gold and copper. The ratio between gold and copper in each alloy is given below.
Alloy A (G : C)----> 2 1/3 : 3 1/3
Alloy B (G : C) ----> 3.6 : 4.8
In which alloy do we have more gold ?

Answer 1

Answer:

Let 100 gm of alloy A and 100 gm of alloy B

Gold  in alloy A=97×100

copper in alloy A=92×100

Gold in alloy B=187×100

Copper in alloy B=1811×100

Gold in alloy C=9700+18700=182100

Copper in alloy C=9200+181100=181500

Ratio of copper and iron in alloy C=182100:181500
