Exam-Style Question on Percentages
A mathematics exam-style question with a worked solution that can be revealed gradually
Question id: 537. This question is similar to one that appeared on a GCSE Higher paper in 2019. The use of a calculator is allowed.
Zoe invests £5000 in an account for one year. At the end of the year, interest is added to her account.
Zoe pays tax on this interest at a rate of 25%. After the tax has been taken off she received £25.40 interest.
Work out the percentage interest rate for the account.
The worked solutions to these exam-style questions are only available to those who have a Transum Subscription.
Subscribers can drag down the panel to reveal the solution line by line. This is a very helpful strategy for the student who does not know how to do the question but given a clue, a peep at the beginnings of a method, they may be able to make progress themselves.
This could be a great resource for a teacher using a projector or for a parent helping their child work through the solution to this question. The worked solutions also contain screen shots (where needed) of the step by step calculator procedures.
A subscription also opens up the answers to all of the other online exercises, puzzles and lesson starters on Transum Mathematics and provides an ad-free browsing experience.
