Division by 25

Bilal's method:
1. Divide last 2 digits of the number by 25.
2. Multiply the number formed by the remaining digits by 4.
3. Add the results obtained step 1 and step 2.

Example1: 725 � 25.
Solution:   725 � 25 = 29 (suddenly)
                 Let's me explain.
                 725 � 25 = (7 � 4) + (25 � 25) = 28 + 1 = 29.

Example2: 3275 � 25.
Solution:    3275 � 25 = 131 (suddenly)
                  Let's me explain.
                  3275 � 25 = (32 � 4) + (75 � 25) = 128 + 3 = 131.
