I wanted to buy a toy. I had four identical coins but these were not enough to pay for what I wanted, so I gave the shopkeeper a $10 note. He gave me two identical coins as my change. If I had had those coins before I could have paid the exact amount.
What could the coins I had before I bought the toy have been?
