A chemist combines three solutions with active

Q: Answer-A chemist combines three solutions with active ingredient concentrations of 10%, 20%, and 30% in the...

Let the volume of these three solutions be 2x, 3x and 5x. 2x3x5x 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 123690 138 Concentration in resulting solution 138600 100 23

ingredient concentrations of 10%, 20%, and 30% in the ratio 2:3:5. If the total volume of the mixture is 600 liters, calculate the concentration of active ingredients in the resulting solution.

A 15%

B 21%

C 23%

D 25%

E 27%
