Question

sets of 12 bottles per box were packed in 25 boxes. if the same batch is packed with 20 bottles in each box, how many boxes would be filled?

Answer 1

Number of bottles in 1 box =12
Number of boxes = 25
:. Total number of bottles = $12 \times 25$
=300

now, after changing the method.
Number of bottles in each box = 20
:. Number of boxes = 300/20 =15 (answer)

I hope this may help..
