@abhishekmehta4u your solution is incomplete. 

 answer will be more then 7 

because you did not include the schedule from T2--->T1

@Gurdeep Saini no man the ques is asking for number of conflict equivalent schedules ,which are equivalent to the given schedule ,in this schedule given the conflicts are always from T1 >T2 and not other way .

but my doubt is why not the ans be 6 instead of 7,becoz one schedule is already given in the ques to us ,and the ques is asking about number of number of conflict equivalent schedules ,which are equivalent to the given schedule,please resolve this doubt @abhishekmehta4u
