I am unsure about the last sentence in the problem. However, I can answer the first part.
First, we need to figure out the total of pens that he gave away.
52 - 20 = 32 pens given away
Since we know he divided them among 4 friends, then we should divide the 32 by 4.
32 ÷ 4 = 8
Stanley gave 8 pens to each of his friends.
