Hiya, Hope you guys don't mind me asking here! I'm currently in the process of interviewing for a job at HMRC and there are Maths/English tests. I was told by a friend there would be questions on Money exchange. I'm so stumped on how to work things out. I'm OK at maths, not great. If for example, 100 Euros is 124.68 dollars and 156.61 Australian Dollars, what is $40 US dollars in Australian Dollars? How would I go about working that out? Sorry if this is really simple!
