One 250mg tablet is made up of chemical A , B, ,C in a ratio 3:2:5. The Pharmacist Has 60mg of chemical B left. How much of Chemical A and C does she need if she uses 60mg of B?

3+2+5 = 10
250/10 = 25

75:50:125 is the required ratio for one tablet

we have 60mg of B, which is enough for 1.2 tablets

So, in theory, if she uses 60mg of B, she will end up using

90:60:150 mg of A:B:C

But who makes 1.2 pills?
