PC disks

Peter has 45 disks in three colors. One-fifth of the disks are blue, red are twice more than the white. How much is blue, red and white disks?

Correct answer:

b =  12
c =  24
m =  9

Step-by-step explanation:


m+c+b=45
m=45/5
c = 2b

m+c+b=45
m=45/5
c = 2•b

b+c+m = 45
5m = 45
2b-c = 0

b = 12
c = 24
m = 9
