Question

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

plz answer it clearly. ​

Answer 1

Given that:

Medicines are packed in boxes. One box weighs 4kg 500g.

We need to find many the number of boxes that can be loaded in a can that cannot carry beyond 800kg.

Solution:

The weight of one box = 4 kg 500 g = 4 × 1000 g + 500 g = 4500 g { As we know that 1kg = 1000g}

Maximum load can be loaded in can = 800 kg = 800 × 1000 g = 800000 g

Hence total weight=Maximum load can be loaded in can =800000 g

Number of boxes = $\frac{Total\: weight } {Weight \:of \:each\: box}$

Number of boxes = $\frac{800000}{4500}$= 177

Number of boxes = 177

Therefore, 177 boxes can be loaded in a can that cannot carry beyond 800kg.

Answer 2

Given :-

Medicine is packed in boxes weighing 4kg 500g.

⠀⠀⠀⠀⠀⠀⠀

To Find :-

How many such  boxes can be loaded in a van which cannot carry beyond 800kg?

⠀⠀⠀⠀⠀⠀⠀

Solution :-

→ Weight of 1 box = 4kg 500g

⠀⠀⠀⠀⠀⠀⠀

1kg = 1000g

4kg = 4 x 1000g

4kg = 4000g

⠀⠀⠀⠀⠀⠀⠀

Weight of 1 box = 4000 + 500

= 4500g

⠀⠀⠀⠀⠀⠀⠀

→ Weight that can be loaded in van = 800kg

= 800 x 1000

= 800000g

⠀⠀⠀⠀⠀⠀⠀

$\sf \rightarrow No. \:of\: boxes\: = \frac{weight \:van\: can\: carry}{weight \:of\: of\: 1\:box}$

$\sf \rightarrow No. \:of\: boxes\: = \frac{800000}{4500}$

⠀⠀⠀⠀⠀⠀⠀

= 177

⠀⠀⠀⠀⠀⠀⠀

∴ Van can carry 177 boxes.
