Question

Peter is unaware that his computer has a virus. Every time he shuts down, the virus deletes half of his hard drive. Peter has also decided that he will have a ‘clean-up’ to free up some of his computer’s memory. Each time he uses his computer, he transfers 2 GB of work onto a USB drive (hence deleting this from his hard drive) and then shuts down. Soon after, Peter gets a message: ‘Hard drive wiped’. He realises his computer must have a virus because he hasn’t saved or deleted any work since he started his clean-up, and he is certain he had much more work than the 10 GB that has been transferred to the USB drive in front of him. How much work (in GB) has Peter lost?
GB
