The topic is compound interest and depreciation. I could answer the other questions on the topic but this just confused me. :/

If the question asked for the amount at the end of two years if the interest is 5% with an initial amount of £1000 then you would do

In this question we're missing the "1.05" part so call that x then

Solve this to find . Then see if you can work out what the interest percentage must be.
