How about you find the vector sum, rather than me.

Or at least post what you've done, and why you're stuck, rather than expecting me to do your course for you.
3. In questions like this, it's useful to draw a diagram. What've you done so far?
4. I calculated the vector sum by taking the origin as reference but couldnot get the answer.
5. you only have 3 directions:

---, / and \ direction! just label each one x,y and z and work from there!
6. first make a diagram - be accurate
then make a note of all the vectors, i.e. what they are
the important bit - you should see a similarity between all/some of the vectors - keep a note of this

simple as pi(e) - 3.1415926535897932384626433...
