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

We know, 1 kg = 1000g

Thus, 4 kg 500g = 4500g

And, 800 kg = 800×1000 = 8,00,000g

Weight of one box = 4500g

The total weight that can be carried by van = 8,00,000 g

Thus, the number of boxes that can be loaded in the van = 800000÷4500

Hence, 177 boxes can be loaded in the van.
