Question

Select a way by which you can make balance of the weight of 2 kg.

Answer 1

We know 1kg = 1000 g, 2kg = 2 × 1000 g = 2000 g
Now in order to balance the weight we need to add weights on the left side such that it adds upto 2000 g.
One such way is to choose 2 weights of 500 g each and 1 kg which are available
One more possible combination is choosing weights of 1kg, 500 g and 2 weights 250 g.
