what is the sum of all 5 digits numbers which can be formed with the digits 0,1,2,3,4 without repetition
Choose the correct choice:
A) 2599980
B) 2699980
C) 2799980
D) 2509980
E) 2499980
There is a simplest formula for solving these type of questions when we are using numbers along with 0 for finding sum.   i,e........(sum of numbers)*{(n-1)!*(111...........n times)-(n-2)!*(111..........(n-1)times) }   so,here by putting the values as,   (0+1+2+3+4){(5-1)!*(11111)-(5-2)!*1111}   = 10{(4!*11111)-(3!*1111)}   = 10{266664-6666}   = 2599980   2599980NSWER:2599980
