Diluted Paint

Solution

Since the yellow tint is at the heart of this problem, let's first find out how much of the yellow tint were there at the outset. 30 percent of 30 liters equals 9 liters. The addition of 5 liters of the yellow tint had a double effect. First of all the amount of the yellow tint grew to 9 + 5,9,5,14,30,35,25 = 14. Secondly, the total amount of the mixture grew from 30,9,5,14,30,35,25 to 35. The problem has been reduced to finding the percentage of 14,9,5,14,30,35,25liters out of the total of 35.

14 / 35,9,5,14,30,35,25 × 100% = 40%.

As might have been expected, the percentage of the yellow tint grew from 35% percent to 40%.
