photo copies in 2 min=20
photo copies in 1 min=(20 divided by2)
=10 photocopies
photo copies in 5min= 10 multiplied by5
= 50
" " in 14 min= 10 multiplied by 14
= 140 photo copies
hence,5min=50 copies and 14min=140 copies

Answer:
if it takes 20 photocopies to zerox in 2 minutes.
then
it would also take 20 photocopies to zexos in 120 secs.
Number of photocopies per sec =120/20
= 6
so number of photocopies in 5 minutes = 300x6= 1800
number of photocopies in 14 minutes = 840x6= 5040
