Question

a full suitcase weighs 19kg 200g. When empty it weighs 2 kg 500g. What what is a weight of the contents?​

Answer 1

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.

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.
