Problem Solving

On a number line with 5 co-ordinates as -2,-1,0,1,2,
Which has the greatest absolute value?
A -2
B -1
C 0
D 1
E 2

I am confused. Shouldn't both A and E have same (greatest ) absolute value ? How can we choose one answer.

Well, it is certainly a bad question. Absolute distance is the distance from the 0 of the number line. So, yes the answer could be A or E.

This is a question from OG 11, can it have an incorrect question in there?
Dont remember the question number but I believe its somewhere between Q 11-20.

Did the question also have a diagram?

If not, the question makes no sense at all.

A B C D E

Apologise for my number line diagram above, but this is given with the question with points A B C D E equidistant from each other.

So the question says
which point A, B,C,D , E has the greatest absolute value.

(btw its question no 20 in OG edition 11)

thanks

oh..the number line did not appear with proper formatting...
hope you got the idea. 5 points on number line marked a b c d e as -2,-1,0,1,2 respectively.

you have misinterpreted the diagram. the correct answer is a) A: -2.

point A on the line lies directly 2 spots away from 0. Point B lies just over 1 spot away, point C lies directly on 0, point D is slightly greater than one spot away, and Point E is just under 2 spots away.

Because of this we see that point A is furthest away from 0, therefore has the greatest absolute value.

I think your mistake was that you thought point E was exactly 2 away from 0, but looking at the diagram you see the arrow points to a spot on the line just before 2.

Hope that helped!

dont really understand. :
i measured the diagram also...all points are equidistant


anybody ??

Hi rainbowlife,

You might have measured the markings on the numberline which are obviously same. What question is asking is the arrow pointing to a point.You will notice that arrow named E is slightly between markings 1 and 2 while the arrow named A is exactly on marking -2. Thus the point E is not exactly 2 but between 1 and 2 (1.8 approximately)
Now you can see why the answer is A and not E

Hope it helps

Thanks

I also have the OG 11th edition and got stumped with this question and its corresponding answer. The diagram has the arrows perfectly above the numbers on the line.

I think they messed up this question. Absolute value of -2 and 2 are the same distance from 0. I can scan the diagram if needed. E is directly above 2.

I can guarantee this about the OG.

There are atleasat some editions that have the diagram drawn brutally wrong.

I can see why some you think it could be -2 or +2. I was also stumped when I saw certain editions of the book with the badly drawn diagram.

Ofcourse, there are some OG books with the correct diagram.

Detonate and Rainbownlife, you are both absolutely right, in that the diagram is wrong.

so many replies to this post.

there is one problem on number line..probably you are referring to that.
