Answer:
9
Explanation:
A number is divisible by 11 if the difference of sum of the digits at odd places and sum of digits at even places is 0 or a multiple of 11.
6+5 - (2+x) = 0
=> 11 - 2 - x = 0
=> 9 - x = 0
=> x = 9
Hence, 9 is the least number that should replace the blank so that the number is divisible by 11.
