Given:

Ravi purchased 5 kg 400 g rice, 2 kg 20 g sugar and 10 kg 850 g flour. 

To do:

We have to find the total weight of his purchases.

Solution:

We know that,

$1\ kg=1000\ g$

Therefore, 

Weight of rice purchased $= 5\ kg\ 400\ g$

$= (5 + \frac{400}{1000})\ kg$

$=(5+0.4)\ kg$

$= 5.4\ kg$

Weight of sugar purchased $= 2\ kg\ 20\ g$

$= (2 + \frac{20}{1000})\ kg$

$=(2+0.02)\ kg$

$= 2.02\ kg$

Weight of flour purchased $= 10\ kg\ 850\ g$

$= (10 + \frac{850}{1000})\ kg$

$= 10.85\ kg$

The total weight of his purchases is,

  $5.400$

$+2.020$

$+ 10.850$

-------------

  $18.270$

-------------

The total weight of his purchases is $18.27\ kg$.
