Actually there is no solution for this question because we know that sum of any two odd numbers is an even number. But here the sum of five odd numbers is an odd number, if the resultant number was an odd number then we would get the answer.
there is a answer for this .only one student have solved this
no it is not at all possible the logic which i have written is absolutely correct
actually, shravs10, it is possible! It's not really math, its a trick question
3 weeks + 7 days + 11 hrs + 13 hrs + 1 day = 30 days!

But anyway, mathematically impossible!
