Two people steal some money from the bank and they divide it among themselves and they find there is 1$ left out .
Then they call another friend and they divide among themselves and they again find out that 2$ are left out ... and again they call another friend and again 3$ are left out and so on .. till they find an 11th person ... after which the money equally divided .

so .. when 2 people divide the remainder = 1

                3 people =2
                4 people =3
                5 people =4
                6 people =5
                7 people =6
                8 people =7
                9 people =8
                10 people =9

and when the 11th peson comes it divided equally ... so you tell me how much money did the thieves took from the bank ??
