The sketch to illustrate the question is given below
Since each of the bags are filled equally with 2 kilograms 450 grams of sand
Then we can sum two bags and compare the mass with 5 kilogram
We can see that the sum of two bags weighs 4 kilograms and 900 grams (4.90 kilograms) which is 100 grams less than 5 kilograms.
Thus we can conclude that the mass of 2 bags is LESS THAN 5 kilograms
