Question

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.

cipher · Answer

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 ?

maliyeci · Answer

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

cipher · Answer

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

Economist · Answer

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. 111.JPG

maliyeci · Answer

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

Economist · Answer

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!

cipher · Answer

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 !

cipher · Answer

Yes, the OA is E, infact I just assumed the 3rd side to be 5 .. my bad

Anyway Thanks.. Cheers !
