Well it sounds like you mean smaller, not greater. 3/300 = 1/100 while 3/30 = 1/10. So 3 out of 300 is 10 times SMALLER than 3 out of 30. 
        
                    
             
        
        
        
Answer:
Let x be the unknown quantity of 50% silver.
Look at the silver concentrations...   This will be 0.5x of actual silver,
Added to 5% silver in 500g or 0.05(500)g of actual silver
Totaling to (500+x)g of 20% silver which will have 0.2(500+x)g of silver
 
Your equation is:
 
0.5x + 0.05(500) = 0.2(500+x)
 
Solve for x to find the grams of 50% silver used
