Find the ratio of alcohol and water in the mixture.​

Answer 1

Answer:

16:29

Step-by-step explanation:

First drink:

Ratio = 2:3

Amount of alcohol = 30* 2/5 = 12 ml.

Amount of Water = 30*3/5 = 18 ml.

Second drink:

Ratio = 1:2

Amount of alcohol = 60* 1/3 = 20 ml.

Amount of Water = 60* 2/3 = 40 ml.

Now in final mixture:

Amount of alcohol = 20+ 12 = 32 ml.

Amount of water = 18+40 = 58 ml.

Total amount of mixture = 90 ml.

Ratio = 32/90 : 58/90

         = 16:29
