Question 10

Q10) 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?

Solution 10:

Weight of a box = 4kg 500g

= 4\times1000\ +\ 5004×1000 + 500 = 4,500g

Weight that can be loaded in van = 800kg

=\ 800\times1,000\ \ =\ 8,00,000g= 800×1,000 = 8,00,000g

No. of boxes that can be loaded =

8,00,000\div4,500\ =\ 1778,00,000÷4,500 = 177

Therefore,

177 boxes can be loaded in the van.

Step-by-step explanation:

Solution 12:

Capacity of glass = 25ml

Capacity of vessel = 4l 500ml

=4\times1,000\ +\ 500\ \ \ =\ 4500ml=4×1,000 + 500 = 4500ml (1l = 1,000ml)

No. of glass that can be filled = 4,500\div25\ =\ 1804,500÷25 = 180

Therefore,

180 glasses can be filled by the vessel of curd.
