Question

Given that 52 x 66 is divisible by 9, where
x is a digit find the possible value of x​

Answer 1

Ans
If

52x66 is divisible by 9
Then
It must apply the divisibility rule of 9 I.e. sum of no should be divisible by 9…

5+2+x+6+6
=19+x
Therefore
Nearest no of 19 which can be divisible by9 is 27
So
19+x=27
X=27-19
=8
So x=8

Therefore
The no is 52866
