Help please from anyone who understands interest!

[Ruple]

If I have a loan of £30,000 and the interest I am paying monthly on that loan is £110.20 a month, what is the interest rate please? I do not have a maths brain or any understanding of how this is worked out. Thanks

Memories of doing actuarial exams which included a paper which was basically "communicating to the layman" and a typical question might be to imagine writing to your aunt who wanted to understand how her mortgage payments worked...
