I don't understand this please explain

Financial Institutions and Financial Markets Interest Rates and Asset Prices The interest rate on a financial asset is the interest received expressed as a percentage of the price of the asset. For example, if the price of the asset is $50 and the interest is $5, then the interest rate is 10 percent. If the asset price rises (say to $200), other things remaining the same, the interest rate falls (2.5 percent). If the asset price falls (say to $20), other things remaining the same, the interest rate rises (to 25 percent)
