Step 1: Take any 4 digits number,such that at least 2 of its digits are different. Step 2: Write the digits in ascending order. Step 3: Write the digits in descending order. Step 4: Find the difference between the two resulting numbers. Step 5: Repeat Steps 2,3 and 4 for the resulting difference we get in step 4. In less than 8 steps you sall get 6174. Work it out for yourself. eg: Take the number: 4884 Ascending order: 4488 Descending order; 8844 Difference: 4356 Ascending order: 3456 Descending order; 6543 Difference: 3087 Ascending order: 0378 Descending order; 8730 Difference: 8352 Ascending order: 2358 Descending order; 8532 Difference: 6174 Can anyone say what would be the case for 3 digited numbers?????E.g If I take 7526, the ascending order form is taking the smallest digit first, to the biggest diggit last. In this case, its 2567.
E.g If I take 7526, the descending order form is taking the biggest digit first, to the smallest diggit last. In this case, its 7652.
In the example in steps 2 and 3, we are doing the following operation:-
7652-2567

hey wats this ?! i din get... but seems vry interesting .... !!
@ anonymous: This is an property of 4 digited numbers. if u take any 4 digited number and follow the above steps u will land up getting 6174 in less than 7 steps.. try yourself( bt not multiples of 1111 ofcourse because they will give the same number in ascending and descending order)
