This is a problem on  a venn diagram in which the problem determines the number of subscribers that are mutually heeding for channel A and channel B. The equation to be followed is 
U = U' + A + B + AandB
Substituting,
8500 = 5140 + 2450+1980- AandB
AandB = 1070 subscribers
        
             
        
        
        
Since it’s 224% just put it over 100 and now convert it to a mixed number with would be 2 24/100 and now simplified which is 2 6/25
So the answer is 2 6/25
