Kinda difficult math question

<p>I'm having a trouble understanding this math problem. Help me out, guys. </p>

<p>There is a stretch of fencing that is 500 feet long. If fence posts are placed at each end and also placed every 5 feet along the fence for support, how many fence posts in all are there in this stretch of fencing? </p>

<p>It's a grid-in question.</p>

<p>5 goes into 500 100 times so then you’re just missing the one at 0 feet. So is it 101?</p>

<p>101 is correct. You have to be inclusive for that last post. Just like how the number of numbers between 1 and 4 inclusive isn’t 3, but 4, if that makes any sense.</p>

<p>Yes, that’s correct :slight_smile: But why do you miss the one at 0?</p>

<p>this is the stupidest question to ask :smiley:
no offence mate. its just that high school students(are you in high school btw?) dont ask such silly and easy questions.
the answer is 101 btw. </p>

<p>and dont take me seriously. i was just trolling around.</p>

<p>But that’s the 14th question out of 18. So it’s considered kinda difficult coz’ many students have already made mistakes on this one on experimental sections.
Akashdip, if you are that smart, I wanna hear your explanations???</p>

<p>^@akashdip I remember my first trolling attempt</p>

<p>anyway @eatlovepray, I wish you were here in real life because this is the type of problem that I can verbally explain while simultaneously drawing a diagram. </p>

<p>but I’ll try my best to explain my thought processes. First, I visualize in my mind a 500 ft. fence. I imagine myself at the very beginning of it with a handful of posts. Every 5 feet that I walk, I will put in a post. (I’ll save the endpoints for the end if I still need to add them). Every 5 feet I walk represents 5/500 of the entire fence. Every time I walk the 5 feet and put in a post, I imagine myself taking a “chunk” out of the 500. I know that there are 100 chunks to take out, so I have to walk 5 ft and put a post in 100 times. once i do it the 100th time, I am at the very end of the fence. But since the very beginning of the fence didn’t have any fence preceding it, it didn’t count as a chunk of 500. but it is an endpoint, so I have to add one there…</p>

<p>Okay I just re-read that and it sounded sooo confusing. Sorry i tried my best haha…</p>

<p>oh cool down bro. i said i was trolling around
anyway have you seen how many lines are there in a 15 cm or 6 inch ruler. its 16(for cm) and 7(for inch). people tend to forget to count the zero mark. same principle bro. just be sane and use your brain. no need to hyperventilate in the exam hall. it just makes you less sane. and the result is you get it wrong.
and as i said i wasnt trying to insult you. just trolling around.</p>

<p>yeah also a ruler is a great analogy. That should help. They have lines at certain increments (every 5 feet in your example) and they have lines at both endpoints.</p>

<p>once i do it the 100th time, I am at the very end of the fence. But since the very beginning of the fence didn’t have any fence preceding it, it didn’t count as a chunk of 500. but it is an endpoint, so I have to add one there…
This part makes a lot of sense. Now I see it. Thank you so much :)</p>

<p>you see @eatlovepray its all very simple. just keep your cool while answering questions. such reasoning tests are mainly to test how you apply your brains. use you common sense. no use fretting since you cant make your brain multitask, both fretting and answering questions at the same time :D</p>

<p>btw i dont think you are still in high school.</p>
