Let the volume of these three solutions be 2x, 3x and 5x. 2x+3x+5x = 600 10x = 600 x = 60 so, the volume of these three solutions are 120, 180 and 300 liters active ingredient in resulting solution = 10% of 120 + 20% of 180 + 30% of 300 = 12+36+90 = 138 Concentration in resulting solution = 138/600 ×100 = 23%
