Question

Choose from the weights above to make the two pans equal. In how many ways can you do it?

Draw the weights in the empty pan. Remember, 1kg = 1000 g  

Answer 1

We know 1 kg = 1000 g

Thus, 2 kg = 2 ×1000 g = 2000 g

Following are the different ways in which we can make the two weights equal - 

1. 1 kg + 500 g + 500 g = 2000 g
2. 1 kg + 500 g + 250 g + 250 g = 2000 g
3. 1 kg + 500 g + 250 g + 200 g + 50 g = 2000 g
4. 1 kg + 500 g + 200 g + 200 g + 100 g = 2000 g
5. 1 kg + 250 g + 250 g + 250 g + 200 g + 50 g = 2000 g
   We can make five different combinations to get 2 kg weight.
