What percentage of those surveyed, viewed more than one of the three TV channels?

1. 16
2. 38
3. 27
4. Data Inadequate

Explanatory Answer

a + b + c + d + e + f + g = 73
g =11
SP + S + SAB = 38 + 39 + 23 = 100
a + e + g +d + b + e + f + g + c + d + f +g = 100
a + b + c + d + e + f + g + 2(d + e + f) + 2g =100
73 + 2(d + e + f) + 22 = 100
d + e + f = 5
More than 1 channel = d + e + f + g = 5 + 11 = 16%

The answer is '16'
