If we draw boxes, there will be 10 boxes for stickers (100%) and 6 boxes for erasers (60%).
10 erasers and 10 stickers were removed and then there were twice as many stickers as erasers.
So the number of boxes removed from erasers and stickers must be the same. Remove 2 boxes from each, then stickers will be left with 8 boxes and erasers will be left with 4 boxes. So this will give us twice as many stickers as erasers.
2 boxes = 10,
1box= 5
Final answer: 5 multiplied by 16 = 80
