If I know that I want to buy 50 GRPs worth of outdoor advertising and the population for my target market is 200,000, what should my daily effective circulation (DEC) amount to?

100,000          

Explanation:

Data provided in the question

Number of GRPs buyed = 50

The population of the target market = 200,000

Now the daily effective circulation is

Number of GRP buyed = (Daily effective circulation) ÷ (Population of the target method) × 100

50  =  (Daily effective circulation) ÷ (200,0000) × 100

So, the daily effective circulation is 100,000
