G goes for seminar in the month which have odd number of days but not in January. Four persons goes for seminar between G and H. G goes for seminar before H. We will have two cases: If G goes for seminar on 12th March, then H will goes for seminar on 25th June. If G goes for seminar on 25th March, then H will goes for seminar on 12th July. A goes for seminar just before E. E did not go for a seminar on an even date.  F goes for seminar just after C but not in April and January. Only three persons goes for seminar between B and F. E and F goes for seminar on the same date but different months. If F goes for seminar on 25 th July, then B will goes for seminar on 25 th April and C will goes for seminar on 12 th July. E will goes for seminar on 25 th January. If F goes for seminar on 12th June, then B will goes for seminar on 12th March and C will goes for seminar on 25th April but this case will get discarded as we cannot place E. I goes for seminar in the month which has odd numbers of days. D goes for seminar on an even date of the month which has even number of days after E. Only two persons goes for seminar between I and J. I goes for seminar on 25th March. J goes for seminar on 12th June. D goes for seminar on 12th April.
