This question relates to a problem in the Maths Challenge for Young Australians and students are not allowed to seek answers in this manner. There is no point in doing the challenge if all you are getting is other people to answer the questions for you. Eventually, if you cannot do the problem, your teacher will have the correct solutions and can talk you through it. There is nothing to be gained by cheating as there are no prizes.
