Note the following points.
(i) x\mod 25 means the remainder when x is divided by 25 .
(ii) Any multiple of 25 will end with either 00 or 25 or 50 or 75
So it doesn't matter how big the given number x is, just by observing the last two digits we can find the remainder when it is divided by 25 .
Here, in the given number 52 is the last two digits. And 52= 50+2 , that is, 2 greater than a multiple of 25 .
So when we divide the number x by 25 , the remainder will be 2 .
That is x \mod 25 = 2
