Squaring of any 4 digit number ending in 25

     Golden Rule:-
                    First part of ans is obtained in four steps.
                    First Part :- Square the first digit of  the given number.
                    Second Part :- Find the product of  first two digits and double it.
                   Third Part :-  Add 5 times first digit  to square of second digit.
                    Fourth Part :- 5 times the second digit.

  Last Part of  ans will be always 25 squared =625.
  In general :- pk25 squared =?
                         =p^2 /2pk /5p +k^2 /5k /625

Consider for example :-
                   1325  squared = 1^2 /2 (1)(3) /  5 (1)+3^2 /5 (3)/625

It is simple
