i have 3 kg 4 kg and 5 kg on one side and 5 kg and 7 kg on the other side which two tiles do i swap to have the same amount on both sides
To solve this problem, you need to find the two tiles that, when swapped, will make both sides of the scale balance with equal weight.
First, let's add up the weights on each side of the scale:
For the left side, we have 3 kg + 4 kg + 5 kg = 12 kg.
For the right side, we have 5 kg + 7 kg = 12 kg.
Since both sides already have an equal weight of 12 kg, the scale is currently balanced. Therefore, you don't need to swap any tiles to obtain an equal weight on both sides.
