Answer 1

The percentage of yellow tint in the new mixture will be 39.1304...%

Step-by-step explanation

A mixture of 60 liters of paint is 25% red tint, 30% yellow tint and 45% water.

So, the amount of yellow tint
`=(60*0.30)liters= 18` liters.

Now, 9 liters of yellow tint are added to the original mixture. So, the total amount of yellow tint in the new mixture will be:
`(18+9)liters= 27` liters.

And the total amount of the new mixture will be:
`(60+9)liters= 69` liters.

So, the percentage of yellow tint in the new mixture
`=(27)/(69)* 100\% = 39.1304... \%`
