  Who won the race?? --A
  
  Row 2predicted that F will win the race, and row 3 predicted that G will win the race... and its given that none of them predicted correctly for any right position. So, this tells that F and G can not win the race.
  
  So looking at all 5 predictions, A is the only choice who can win the race.

  Answer is A..
  the options 2 and 3 have 0 right positions.
  thats all the positions are wrong..
  this implies F and G never finish 1st.
  since in options 4 and 5 F and G comes 1st respectively.. we are left with the 1st option.. so A comes 1st

  From the figure,
  1: 2 right positions and one wrong position
  Right: A, E Wrong: B
  
  2: 0 right and 1 wrong
  Wrong: E
  
  3: 0 right and 2 wrong
  Wrong: E, C
  
  4: 1 right and 2 wrong
  Right: B Wrong: F,I
  
  5: 1 right and 1 wrong
  Right: F Wrong: A
  
  So A should win the race.
  
  P.S: I don't understand this line "No of participants finishing in 1st through 5th positions that were predicted". Do you mean 5 positions or 5th position?

  from the predictions of line 2 and 3, where the predictions right are 0, we infer that neither of d to k are the winners. that means one of the remaining 3 must be the winner. now, since the winner must be on the right place also at the right forecast, only A fulfills it, that is, at the 1st prediction. so A is the winner.

  From the table, sing trial and error, I came up with the set of 5 persons who actually came in the top 5 positions.
  
  It came to be "B, C, D, I and F".
  
  Now, we need to find the order in which they finished.
  
  Filling these info in the table, we have
  
  [TABLE="width: 200"]
  [TR]
  [TD]1[/TD]
  [TD]--[/TD]
  [TD]B[/TD]
  [TD]C[/TD]
  [TD]D[/TD]
  [TD]--[/TD]
  [TD]2[/TD]
  [TD]1[/TD]

  [TD]D[/TD]
  [TD]0[/TD]
  [TD]1[/TD]
  [/TR]
  [TR]
  [TD]3[/TD]
  [TD]--[/TD]
  [TD]C[/TD]
  [TD]--[/TD]
  [TD]I[/TD]
  [TD]--[/TD]
  [TD]0[/TD]
  [TD]2[/TD]
  [/TR]
  [TR]
  [TD]4[/TD]
  [TD]F[/TD]
  [TD]--[/TD]
  [TD]--[/TD]
  [TD]B[/TD]
  [TD]I[/TD]
  [TD]1[/TD]
  [TD]2[/TD]
  [/TR]
  [TR]
  [TD]5[/TD]
  [TD]--[/TD]
  [TD]F[/TD]
  [TD]--[/TD]
  [TD]--[/TD]
  [TD]C[/TD]
  [TD]1[/TD]
  [TD]1[/TD]
  [/TR]
  [/TABLE]
  
  Now, we know from row 2 and 3 that D is not the last and C and I are not 2nd and 4th respectively.
  
  From row 5, either F is 2nd or C is last. Assume one of them, and find if everything is coming correctly. Assuming F is 2nd proved to be correct.
  So, the correct order is B==>F==>C==>D==>I
  
  The original table can be verified with this order to be correct.
  
  So, B came first.. 😀

  The sequence is 1st= I, 2nd= B, 3rd= K, 4th= A, 5th= E.
  
  From forecast:
  
  1 - Right= B (2nd), E (5th); Wrong= A (should be 4th).
  2 - Wrong= E (...5th)
  3- Wrong= I (...1st), E (...5th)
  4- Right= K (3rd); Wrong= I (...1st), B (...2nd)
  5- Right= A (4th); Wrong= E (...5th).
  
  Therefore, I won the race... 😉
