candy distributor needs to mix a 20% fat-content chocolate with a 50% fat-content chocolate to create 100 kilograms of a 23% fat-content chocolate.

Question

How many kilograms of each kind of chocolate must they use?

Answer 1

20% = 90 kilos

50% = 10 kilos

90+10 = 100 kilos

F=100-C

20C+50F = 2300

2C + 5F = 230

2C + 5(100-C) = 230

-3C = 230 = 500

3C = 270

C = 270/3 = 90

F = 100-90 = 10
