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.

Thanks

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

Well I agree but if we use both the statements then we will get shape which is shown in the figure, in that case cant we calculate the distance ?

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.

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.

I can not find the distance with 2 statements. Somebody can show me the calculations?

Hmm...even I am wondering now
We are not given the angle...we only know lengths of two sides....so length of third side can be anything...

OA Pls!

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
