Detailed Solution

Concept- In order to solve the given question we will use formulas to convert the value of goods in one unit system and then add them to find the total value of goods purchased by Ravi.
Here Given ,
Weight of rice

= 5 kg 400 g

Weight of sugar

= 2 kg 20 g

Weight of flour

= 10 kg 850 g

Then,
total weight will be,

= 5 kg 400 g + 2 kg 20 g + 10 kg 850 g

= (5 kg + 400 g) + (2 kg + 20 g) + (10 kg + 850 g)

= (5 kg + 2 kg + 10 kg) + (400 g + 20 g + 850 g)

= 17 kg + 1270 g

= 17 kg + 1000 g + 270 g

As we know that ,

1000 g = 1 kg

Therefore,

= 18 kg 270 g

So, the correct answer is 18 kg 270g.
Hence, the correct option is 3.
