Medicine is packed in boxes, each weighing $ 4 \mathrm{~kg} 500 \mathrm{~g} $. How many such boxes can be loaded in a van which cannot carry beyond $ 800 \mathrm{~kg} $ ?

Given: 

Medicine is packed in boxes, each weighing \( 4 \mathrm{~kg} 500 \mathrm{~g} \).

To do: 

We have to find the number of boxes can be loaded in a van which cannot carry beyond \( 800 \mathrm{~kg} \).

Solution:

Weight of 1 box $=4\ kg\ 500\ g$

$=(4\times1000+500)\ g$          (Since $1\ kg=1000\ g$)

$=4500\ g$

The maximum weight that the van can carry $= 800\ kg$

$= 800 \times 1000\ g$

$=800000\ g$

Therefore,

The number of boxes that can be loaded in the van $= \frac{800000}{4500}$

$= 177$ boxes

Hence, the number of such boxes that can be loaded in a van which cannot carry beyond \( 800 \mathrm{~kg} \) is 177.
