We should see the quality of gold right. Goldsmith 1 = 5/5 + 8 = 5/13 = 0.3. Goldsmith 2 = 3/3+7 = 3/10 = 0.3. So the quality of goldsmith 1 is greater than the quality of gold smith 2

My experience with Abhyas Academy has been very good. When I was not in Abhyas whenever teacher ask questions I could not speak it confidently but when I came in Abhyas, my speaking skills developed and now I am the first one to give the answer of teachers question.
