I've got a question for 4a. Do you get the first M1 for saying 120/(1-r)=480? This is what i did. I didn't say the a/(1-r)=480 that is next to the first M1. Surely what I said implies a/(1-r)=480. Btw I also did end up getting r=3/4 as required.

Thank you:smile:

I'm pretty sure the answer is yes. (It'd help to see the original question, though!)
