A CIRCLE HAS 29 POINTS ARRANGED IN A CIRCULAR FASHION CLOCKWISE FROM 0 TO 28.A bug moves clockwise on the circle by foolowing rule:
if it is point i on the circle it moves clockwise by i+r places, where r is the remainder when i is divided by 17. Thus if it is at point 5, then it moves in one second clockwise to further 1+5; i.e at 11 position. If it is at position 28 it moves to 1+11 i.e 11 position in one second.
If he starts at point 0; where will he be after 2012 seconds?

• ans is 15
  at 1sec o%17+1=1
  at 2 sec 1+1%17+1=3
  at3 sec 3+3%17+1=7
  at 4sec 7+7%17+1=15
  at 5 sec 15+15%17+1=3
  it will repet after 3second
  hence 2012-2=2010
  2010/3
  =0
  hence it will be 15

• thnks to JAYASRI but the positions repeat for every 8 secs (or 8 pos)
  Starting from 0 pos,
  pos. after 1sec=0+(1+0%17)=0+(1+0)=1
  ,, ,, 2sec=1+(1+1%17)=1+(1+1)=3
  ,, ,, 3sec=3+(1+3%17)=3+(1+3)=7
  ,, ,, 4sec=7+(1+7%17)=7+(1+7)=15
  ,, ,, 5sec=15+(1+15%17)=15+(1+15)=31=2
  ,, ,, 6sec=2+(1+2%17)=2+(1+2)=5
  ,, ,, 7sec=5+(1+5%17)=5+(1+5)=11
  ,, ,, 8sec=11+(1+11%17)=11+(1+11)=23
  ,, ,, 9sec=23+(1+23%17)=23+(1+6)=30=1
  so poss repeat for every 8 secs
  2012%8=4

  1 Cycle formed
  
  1-3-7-15-2-5-11-23-1 Every 8 second the bug return to position '1'
  2012-1 (number of digit doesn't involved in the cycle)=2011
  2011/8 = 3 (remainder)
  so the third position in the cycle is '7'.
  hope you've got it.

• the ans is 3..bcoz when he starts from position 0..
  here i=0 and i divided by 17 will also give zero.therefore i+r(0+0) is again zero and hence its first move is only zero and will not be able to move further as this continues for infinite seconds.
  therefore,ans is ZERO.
