I am trying to solve the problem :
A single fence is to be constructed from posts 6 inches wide and separated by lengths of chain 5 feet . If a certain fence begins and ends with a post.Which of following could be length of fence in feet ? a)17 b)28 c)35 d)39 e)50. (Ans:a,b,d and e)
Since the total space from one fence to another would be 6ft. I believe the fence size should be a multiple of 6 .None of the nos here are multiple of 6. How did they get the answer above ?
