Answer:
D. 282.86 GRPs
Step-by-step explanation:
Recall that
Reach = (Persons reached/ total population) × 100
Where persons reached = 9900
Total population = 70000
Thus
Reach = 9900/70000 × 100
= 0.14142857 × 100
= 14.142857
GRPs = Reach × spot
Where
Spot = 20
Reach = 14.142857
Therefore,
GRPs = 20 × 14.142857
= 282.857143
=282.86 GPRs
