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

1000×1.0521000 \times 1.05^2


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

2500×x2=27042500 \times x^2 = 2704

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