if it is divisible from 11 then x value is 6

Aditi26703: but how
s7388: towards left hand side from unit place add the numbers of even place and then do the same process for odd place the find the difference of both sum. difference should be 0 or
Aditi26703: ok ok i got it
s7388: kindly see here. number is 25x52 in this number even places are 5 and 5 so add it = 10 then find odd places that is 2 ,x and 2 now add this = x+4 now the difference of 10 and x+ 4 is equal to 0 means (4+x)-10= 0 so x = 6
s7388: this is the condition of divisibility by 11.
s7388: hope it will help.
