2a pharmacist has a 13 % alcohol solution and another 18 % alcohol solution. how much of each must he use to make 50 grams of a 14 % alcohol solution

Step-by-step explanation:

Given that , A pharmacist 13% alcohol solution another 18% alcohol solution .

Let he took x gram solution of type solution

and he took (50-x) gram of type solution.

Total  amount of alcohol = gram

Total amount of solution = 50 gram

According to problem

⇔

⇔

⇔- 5x= 700 - 900

⇔5x = 200

⇔x = 40 gram

Therefore he took 40 gram of type solution and (50 -40)gram = 10 gram of type solution.

yes. we do proportions in probabilities.
