What is the smallest 10 digit number which is composed by 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 and can be evenly divided by 11? IS THERE ANY COMMON APPROACH TO SOLVE THIS QUESTION PLEASE EXPLAIN ?

Solution

The number is 1024375869
Sum of all even digits = 0+4+7+8+9 = 28
Sum of all odd digits = 1+2+3+5+6 = 17
Difference = 28-17 = 11
If difference is a multiple of 11 then the number will definitely be divided by 11,
(Here we have to remember one thing also that arrangement of digits should be in such a manner that smaller digits could be used before the greater digits)
If question would be based on the greatest number then number should be
9876524130
