Question

a mixture of 40 liters of paint is 25% red tint, 30% yellow tint and 45% water. 6 liters of yellow tint are added to the original mixture. the percent of yellow tint in the new mixture is?

Answer 1

Since 30% of 40 liters=12 liters of yellow tint
10 +40=50 Total mixture, but since we had 12 liters of yellow tint + 10 new liters=22 liters of yellow tint 22/50=44% of the new mixture is yellow tint. :)
