a.10.150kg
b.22.750kg
c.25.350kg
d.18.250kg

Answer 1

Hint: We have three different weights and the total weight is given by the sum of these weights and to convert the grams into kilograms divide it by 1000 and add it to the existing kilogram.

Complete step-by-step answer:
We are given that Rahul purchased 4 kg 500 g rice , 5 kg 650 g sugar and 12 kg 600 atta
The total weight is nothing other than the sum of all the given weights
Weight of rice purchased = 4 kg 500 g
Weight of sugar purchased = 5 kg 650 g
Weight of atta purchased = 12 kg 600 g
Total weight purchased =$\underline {\overline {22kg{\text{ }}750g} } $
All our options are given in kilograms so lets convert our total weight into kilograms.
Total weight = 22 kg + 750 g
So here we need to convert the 750 grams into kilograms and add it with 22 kg
To convert grams into kilograms we need to divide it by 1000.
$ \Rightarrow \dfrac{{750}}{{1000}} = 0.750kg$
And adding it with 22 kg we get the total weight to be
$ \Rightarrow 22kg + 0.750kg = 22.750kg$
Therefore the total weight is 22 . 750 kg
The correct option is b.

Note: Same way to convert kilograms into grams we need to multiply the kilogram by 1000.
These are derived from the fact 1 kilogram = 1000 grams
