Three different locations are represented on a map by the points X,Y and Z. What is the actual distance between the locations represented on the map by X and Y ?
( 1cm = 200 KM)
1. Z is to the left of X and Y is to the right of X.
2. X is 4 cms from Z, and Y is 3 cms from Z.
Please explain.
Thanks

E none.
We do not know whether they lie on a line or not. So we can not say anything.

Can't they be on the same line? 3-4-5 triangle is a very special case. You are doing wrong I think.

I agree this is might be a special case and this is exactly what I am want to know where am I going wrong. Anyway the points can’t be on the same line because as per the 1st statement Z is to left of X and Y is to right of X and from the 2nd statement the distance between Z and Y is 3 which is not possible because in that X goes to the right of Y. Cheers

Yes you are right. They can not be on the same line.
But there are unlimited number of triangles with 2 sides are 3 and 4.
It may vary from 3-4-1,000001 to 3-4-6,999999999.
Left of x and right of x may limit to some values. But it does not limit to 3-4-5

Good question. I think answer should be C. Because when we combine 1 and 2, it is implicit that points are not on the same line. For.eg. following figure is not possible. Attachment:

Yes maliyeci you are right, the 3rd side can be 2 or may be 6 ... my bad I assumed that it will be 5 ( general notion while doing questions related to triangles ) Anyway thanks for making me understand ..the new lesson for the day .. i.e STOP Assuming :D Cheers !
