Medicine is packed in boxes, each weighing 4 kg 500g. How many such boxes can be loaded in a van which cannot carry beyond 800 kg

Solution: as we know that , $1000g=1kg$
now, acc to question
weight of each box $=4kg+500g$
$=4000g+500g=4500g$
weight that van can carry = $800kg=800\cdot 1000=800000g$
no of boxes the van can carry =$800000÷4500$
$=177b\otimes es$
