Can someone solve this problem?
There are 'X' boxes containing notes of denominations 10, 20, 50, 100 and 500 in infinite number. Exactly 9 notes are randomly taken from each of the boxes. What is the minimum possible number of boxes needed to make sure that atleast 8 notes of the same denomination are taken in out in total?
