Answers
Answer:
5 bags weigh 150 kg total.
Now to find the weight of 1 bag we apply the unitary method. i.e. divide the total weight by the no. of bags.
150/5 = 3kg.
This gives us the weight bag of 1 bag to be 3 kg.
Now, we need to find how many bags weigh 900 kg.
Assume rhe no. of bags are ‘x’.
We have weight of 1 bag = 3kg.
5 bags weigh 150 kg total.
Now to find the weight of 1 bag we apply the unitary method. i.e. divide the total weight by the no. of bags.
150/5 = 3kg.
This gives us the weight bag of 1 bag to be 3 kg.
Now, we need to find how many bags weigh 900 kg.
Assume rhe no. of bags are ‘x’.
We have weight of 1 bag = 3kg.
It means 3x = 900kg.
Now find x by dividing 900 by 3.
It will give the answer as 30.
This is the answer if the weight of all the bags are same. If the weight of bags are unequal then the answer cannot be calculated using the info given.

Answer:
weight of 16 bags of rice =240kg
Weight of 1 bag of rice =240/16=15kg
No. Of bag will fill by 90kg =90/15=6
That’why no.of bags 6 contain of 90 kg rice
Answer is 6 bags
