X>11
X^2 +1 is devided by 11
which of the following can't be remender
a) 2 b) 3 c) 6 d) 8

• 3 is not there. option b is 4
  and i think ans will be 8
  when we devide the no by 11 than we get 1,2,4,5,6,10 as remender.
  0*0 + 1=1 (eg x=22)
  1*1 + 1=2 (eg x=12 , 23)
  2*2+1 = 5 (x=13)
  3*3+1=10
  4*4+1=5
  5*5+1=4
  6*6+1=4
  7*7+1=6
  8*8+1=10
  9*9+1=5

• i am sure answer will be 8
  3 and 2 and 6 come respectively square of 17^2+1 or 12^2+1 and 15^2+1
  that why answer must be 8
