Answer 1

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

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 $=\frac{27}{69}\times 100\% = 39.1304... \%$
