Actual calculation is (1500*((100-20)/100)
20% = .20.20*1500 = 300
15 = 1500% 20 = 2000%

20% = .20.20*1500 = 300
A pharmacist mixed a 20 percent solution with a 30 percent solution to obtain 100 liters of a 24 percent solution. How much of the 20 percent solution did the pharmacist use in the mixture (in liters).

The answer is 20%. The work is 300/1500 = .2 x 100 = 20%.
300/1500 * 100 = 20Therefore 300 is 20% of 1500.
20% of 1500.00= 20% * 1500= 0.2 * 1500= 300.00
