Question

In a mixture of water and alcohal are in the ratio 3:5. In 72 gallons of mixture , what are the quantities of water and alcohol​

Answer 1

Answer

the amount of water in the misture = 72/3

                                                         = 24 ml

the amount of alcohol in the mixture = 72/5

                                                             =14.4ml

Answer 2

Answer:

Step-by-step explanation:

The ratios are given such that the sum of alcohol and water can be brought up to 10 for each mixture. (Since equal quantities are to be added)

For 3:2 lets take 6 parts alcohol and 4 parts water

For 4:1 lets take 8 parts alcohol and 2 parts water  

For last since the sum is already 10, 7 parts alcohol and 3 parts water.

Mixing these three will give 6+8+7 =21 units alcohol and 4+2+3=9 units water

or, 21 units alcohol in 30 units of mixture

21/30 *100 = 70%
