Answer: There are 96 green pens sold.

Step-by-step explanation:

Since we have given that

Number of pens in each pack of black pens = 3

Number of pens in each pack of red pens = 5

Number of pens in each pack of green pens = 6

Ratio of number of packs sold of black, red and green pens = 7: 2: 4

Number of total pens sold = 220

So, ratio of pens in number of packs would be

$7\times 3:2\times 5:4\times 6\\\\=21:10:24$

So, Number of green pens sold would be

$\dfrac{24}{55}\times 220\\\\=24\times 4\\\\=96\ pens$

Hence, there are 96 green pens sold.
