Q.10. 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?

Weight of one box = 4 kg 500 g
= 4 × 1000 + 500 = 4500 g
Maximum weight carried by the van
= 800 kg = 800 × 1000 = 800000 g.
Hence, number of boxes that can be loaded in the van =\(\frac{ 800000}{4500} \)= 177 boxes
