Let's say in the first year, no of copies sold \(= 6x\)
In the second year copies sold \(= x\) & in the third year \(= 3x\)
Average of second & third year \(= 2x\)
The first year copies are three times the average of second & third year.
Answer D
In the second year copies sold \(= x\) & in the third year \(= 3x\)
Average of second & third year \(= 2x\)
The first year copies are three times the average of second & third year.
