Let the quantities of the paints A and B in the mixture sold be a litres and b litres respectively. Value at which the entire mixture is sold =264 Profit percent made =10% Value at which the entire mixture is bought =264×
100
110
=240 Price at which the entire mixture is bought =24 per litre Let the cost of B be x per litre. Cost of A=(x+8) per litre
(x+8)a+xb
10
=24 Maximum cost of B will occur when a is minimum. b<=a. So, minimum a is 5. Corresponding b is 5 . Then (x+8)(5)+x(5)=240x=20
