  2. Sir I’m extremely, extremely grateful for your posts, this blog has helped me immensely and I’m going to follow it even after my CAT this year because I’m just a smarter person thanks to it! I’m looking forward to the circles plotting post, sir! Would be lovely if you post it anytime soon. I have to write the CAT on the 7th, it would be simply brilliant to take the skills you share with me to the exam.

  3. I did not understand the last question, how did you choose the x and y values to be +/-2? because when we solve the equation:
    x+y+y-x = 4
    we get y=1,
    x+y+x-y = 4,
    we get x = 1
    -x-y+y-x = 4,
    we get x= -1
    -x-y-y+x = 4,
    we get y = -1
    so we get x=y= +/- 1.. plz help
