For, 18th minute problem, solution H is 32% ethanol and 68% water. Solution k is 60% ethanol and 40% water. If 20 grams of solution H is mixed with 30 grams of solution k, ethanol comprises what percent of the resulting mixture?

How do I solve the math using ‘Tug of war’, so far I have done,

H: K= 18: 10 = 9:5 = 5: 9

14 = (x/100) * 50

x= 28%

What wrong am I doing here?

Thank you.
