A batch of bottles were packed in 25 boxes with 12 bottles in each box. If the same batch is packed using 20 bottles in each box, how many boxes would be filled?
Solution:
If 12 bottles each can be packed in 25 boxes, then the total number of bottles is 25 * 12 = 300 bottles.
Number of boxes required to pack 20 bottles in each box are 300 / 20 = 15 boxes.
