    The 12th Question of the #-Link-Snipped-# is as follows -

    [Worth 10 CE Coins]

    Following is the forecast about the order of the positions in which some participants would finish a race.
    The chart below also indicates how correct the forecast was.
    The Question is : Who won the race? i.e. Who reached the finish line first?

    NOTE: You have to tell us the approach you used to get the answer.

    Race
    Solutions goes like this -

    Forecast 1 has 3 of the 1st five position winners.
    Forecast 4, too, has 3 of the 1st five position winners.
    & Forecast 1 & 4, have exactly 1 participant 'B' in common.
    Hence all the 1st five winners are in Forecast 1 & 4 and B is one of them.

    Thus, H & J are eliminated.

    Suppose, D was one of the 1st five position winners. Then, because H is eliminated & from Forecast 2, each of F, G and E was not one of the 1st five position winners.
    Then, from Forecast 5, both A and C were among the 1st five position winners .
    But, from Forecast 1, this situation is impossible.. because B was one of the five and D was supposed to be one of the five.
    So, D was not among the 1st five position winners.

    From Forecast 2 & 5, either A or C was one of the 1st five position winners.
    From Forecast 1, E was one of the 1st five position winners.

    From Forecast 2, both F & G was not one of the 1st five position winners, because E was one of them and H & D were not.

    From Forecast 4, both K & I were one of the 1st five position winners, because E was one of them and F & G were not.

    Then, From Forecast 3, C was not one of the 1st five position winners, because both I & E were.

    Then, From Forecast 1 & 5, A was one of the 1st five position winners because 6 of 11 entrants have been eliminated.

    In summary,

    B, E, K, I, A were the 1st five position winners.

    From 3 & 5 -> A finished 4th.
    From 1 -> B finished 2nd & E finished 5th.
    From 4 -> K finished 3rd.

    Hence I finished 1st! 😉
