What is this question asking for? Can anyone explain what the choices mean? I did get the answer right, but I had to guess.

Help appreciated.

Cheers

PLease recheck your answer.
IMO it should be E.

Yes it is E as posted above.
What in the world is with these answer choices that are given?

I think i get it now that I look at the question carefully

With this question I think it's the law of diminishing returns that applies to me.
I just understood the question. Thanks for the help anyways.

I am sorry, I read your spolier as B. Probably bcoz my mouse cursor was there itself.

Good that you yourself have understood it

I can see the 1, 2,3 and 6 but can somebody please show me 4 and 5 ?

I see the answer as "E"
If you try making a picture of how circle can intersect a triangle.

thanks amitabh

Can someone elaborate more in this question?

What is this question asking for?
How to approach it ? i.e drawing the circle and the triangle in a coordinate plane or what?

re-opening this question.

Is there a quicker way of solving this problem.
I had to think of 6 diagrams to satisfy each option from 1 to 6.
Not exactly a time-saver!!

Experts please tell me how you would approach this problem on a time limit.

I didnot understand the question. Can someone please explain.

Hey all,

i think the answer should be B
coz the question says how many points the circle will intersect and not touch.
so we should no consider the case of tangents

hence there will only be either 2 ,4 or 6 points .
hope the diagram makes my clear...
