since a number is divisible by 9 if the sum of its digit is also divisible by 9.
X+5+5+7+X+5+5
=27+X
27 +X is divisible by nine
if X=0 or 9 then the number is divisible by 9

if divisible by 11
if it is divisible by 11 then the difference between the sum of its digit at odd place and even place is either 0 or divisible by 11
