The last question (Q28), there's a formula. If there are 100 lamp posts and they ask for the number of spaces in between, it's always 100-1. The formula is x-1. x can be any whole number. Take your fingers as an example. You have 5 fingers, and only 4 spaces in between them. Hope this helps you with your future exams/ tests.
