Question

Medicine is packed in boxes, each such box weighing $4kg500g.$ How many such boxes can be loaded in a van which cannot carry beyond $800kg$.

Answer 1

$\because$ Total capacity of a van carrying boxes of medicines $=800kg=8,00,000g(\because 1kg=1,000g)$

$\because$ Weight of each packed box $=4kg500g=4,000+500=4,500g$
$\therefore$ Total number of boxes that can be loaded in the van $=\frac{8,00,000}{4,500}=177.77$

The obtained number of boxes is not a whole number.
$\therefore$ Weight of $177$ boxes $=177\times 4,500=7,96,500g$ (under permissible limit)
$\therefore$ Weight of $178$ boxes $=178\times 4,500=8,01,000g$ (beyond permissible limit)

Therefore, we can't load $178$ boxes; hence, we can say that $177$ boxes can be loaded in the van.
