Make the number of bottles and cups the same by multiplying by 5 and 6. One set is 30 bottles and 30 cups, which is 6 boxes and 5 packets. The difference in the number of boxes and packets is 1. To get a difference of 5, you need 5 sets. Hence the number of bottles purchased is 5 sets of 30 bottles.
