Question

If 28 identical boxes weight 84 kg then how many boxes will weight 126 kg​

Answer 1

given:-

28 identical boxes weight 84 kg

Now to find the weight of 1 box we apply the unitary method. i.e. divide the total weight by the no. of boxes.

84/28=3kg

This gives us the weight of 1 box to be 3 kg.

Now, we need to find how many boxes weigh 126 kg.

Assume the no. of boxes are ‘x’.

We have weight of 1 box = 3kg

It means 3x = 126kg

Now find x by dividing 126 by 3.

It will give the answer as 42

hence the required answer is 42
