Advertising Revenue
1. The problem asks which two media together generate £6.15 billion revenue in 2011 based on the pie chart percentages of a total £20.5 billion forecast.
2. From the pie chart, the percentages for each media in 2011 forecast are:
- Television: 21%
- Radio: 4%
- Newspaper: 30%
- Magazines: 9%
- Out-of-home: 5%
3. Calculate the revenue for each media by multiplying the total forecast £20.5 billion by the percentage (in decimal form):
- Television revenue = $20.5 \times 0.21 = 4.305$ billion
- Radio revenue = $20.5 \times 0.04 = 0.82$ billion
- Newspaper revenue = $20.5 \times 0.30 = 6.15$ billion
- Magazines revenue = $20.5 \times 0.09 = 1.845$ billion
- Out-of-home revenue = $20.5 \times 0.05 = 1.025$ billion
4. Check each option for combined revenue:
(A) Television + Radio = $4.305 + 0.82 = 5.125$ billion
(B) Newspaper + Radio = $6.15 + 0.82 = 6.97$ billion
(C) Out-of-home + Newspaper = $1.025 + 6.15 = 7.175$ billion
(D) Radio + Magazines = $0.82 + 1.845 = 2.665$ billion
(E) Magazines + Television = $1.845 + 4.305 = 6.15$ billion
5. The only pair that adds up exactly to £6.15 billion is (E) Magazines and Television.
Final answer: (E) Magazines and Television
