I know how to use a calculator, but being honest, dunno what to put in it to get the answer... So as I don't know, I'll ask here...
Someone puts £1.25 million into a bank account and leaves it there for 10 days. Then they take the money out.
In those 10 days it earns £210 in interest.
What was the yearly interest rate % of the account?
Thanks in advance
