1.	A person preparing a medicine wants to convert 15% alcohol solution into 32% alcoholsolution. Find how much pure alcohol he should mix in 400 mL of 15% alcohol solutionto obtain required solution?3.
Answer» Given Total solution quantity = 400 ml15% alcohol solution contains= (15/100)400 = 60ml alcohol For 32% alcohol solution = (32/100)400 = 128 ml Thus to convert 15% alcohol into 32% alcohol solution amount of alcohol to be added = 128 - 60 = 68 ml

Answer»

Given

Total solution quantity = 400 ml15% alcohol solution contains= (15/100)*400 = 60ml alcohol

For 32% alcohol solution = (32/100)*400 = 128 ml

Thus to convert 15% alcohol into 32% alcohol solution amount of alcohol to be added = 128 - 60 = 68 ml
