Pls me out with this:
1. bernard counted 8 posts along the side of the road. if the posts were 20 m apart, how far is it from the first post to the last?
2. in my block of 100 flats, a painter is kept employed by painting one flat each month from january to november. the flats are painted in the same order and he takes holidays every december. if my flat was last painted in august 2010, when will it be next painted?
