Given :
a/2=b/100*30; a = 0.6*b
A= c/100*50= 0.5*c
B = a/0.6
C= a/0.5
C is greater.
a/2=b/100*30; a = 0.6*b
A= c/100*50= 0.5*c
B = a/0.6
C= a/0.5
C is greater.

You sure this is correct?
What I got:
a/2 = (30 * b)/100; // because we are taking b% of 30 which is 30 * (b / 100). Why this is incorrect?
a = (50 * c)/100;
c = (3 * b) / 10 = 0.3 * b; => c > b.
Where I am mistaken?
Thank you!
