I have a pie chart. divided into 4 sections.
1/4 says A(20%)
1/4 says B (25%)
1/4 says C
1/4 says D
The ratio of C's to D's is 7:4
There are more B's than A's.
How many C's are there?
------------------------
C and D share 55%
The ratio of C to D is 7x/4x
7x+4x=55
11x = 55
x = 5
C = 7x = 35%
D = 4x = 20x
