What would be the concentration if we were to mix 200g of 10% sugar solution and 300g of 20% sugar solution?

+ 200g of 10% sugar solution: there is 200*10% = 20 g

+ 300g of 20% sugar solution: 300*20% = 60 g

The total of sugar: 20+60 = 80g

And The concentration is 80: (200+300) = 80:500 = 16%

Have fun
