Did you ever notice this:-
Step 1: Take any
number N , whose sum of digits
Step 2: Multiply
N by 11 and say resultant as M , N*11 = M
Step 3: Reverse
the digits of M and say it P
Step 4: Divide P
by 11 and say it Q , P/11 = Q
Step 5 : Check N
& Q , Q is reverse of N
E.G.
Step 1: N= 12113
Step 2: 12113*11
= 133243 = M
Step 3: 342331 = P
Step 4: 342331 /
11 = 31121= Q
Step 5 : Check N
& Q , Q is reverse of N
