Question
How many persons attending the seminar between S and
V? Study the following information carefully and answer the below questions. Ten persons namely тАУP, Q, R, S, T, U, V, W, X, and Y attend a seminar event in five different months viz.- January, April, July, September, December. Seminar in each month was scheduled on the 5thrd and 8th of the month. All the information is not necessary in the same order. The number of persons is attending a seminar after P is the same as the number of persons is attending the seminar before R. P attends seminar two months after Q, who attends the seminar on an odd date. R and Y attend the seminar in the same month. The number of persons is attending the seminar between Y and Q is the same as the number of persons is attending the seminar between P and X. The number of persons attending the seminar between U and R is one less than the number of persons is attending the seminar between W and V. U attends seminar three months before X, who attends seminar in one of the months has 31 days. V attends seminar on the 8th┬аof the month but not in January. W and S attend seminars in the same month. At least two persons attend the seminar between T and P.Solution
The number of persons is attending a seminar after P is the same as the number of persons is attending the seminar before R. P attends seminar two months after Q, who attends the seminar on an odd date. R and Y attend the seminar in the same month. We will have four cases: If Q attends seminar on 5th January, then P will attend on 5th April. R will attend on 8 September and Y will attend on 5th September. If Q attends seminar on 5th April, then P will attend on 5th July. R will attend on 8 July but we do not have dates for Y. If Q attends seminar on 5th July, then P will attend on 5th September. R will attend on 8 April and Y will attend on 5th April. If Q attends seminar on 5th September, then P will attend on 5th December. R will attend on 8 January and Y will attend on 5th January.
The number of persons is attending the seminar between Y and Q is the same as the number of persons is attending the seminar between P and X. In case 1, there are five person between Q and Y. So, X attends seminar on 5th December. In case 3, there is one person between Q and Y. So, X attends seminar on 5th December. In case 4, there are five person between Q and Y. So, X attends seminar on 5th April. U attends seminar three months before X, who attends seminar in one of the months has 31 days. Case 1 and 4 will get discarded as we know that X attends the seminar in December and U should have attended in September. In case 3, U attends seminar on 8 September
At least two persons attend the seminar between T and P. So, T attends seminar on 8 December. ┬а┬аV attends seminar on the 8th┬аof the month but not in January. Now it is clear that V attends the seminar on 8 July. The number of persons attending the seminar between U and R is one less than the number of persons is attending the seminar between W and V . W and S attend seminars in the same month. We know that three person are there between U and R. It means that there would have been four person between V and W. So, W and S attend seminar on 5th January and 8 January respectively.
